During transcription, the complementary strand to the DNA sequence ATTCGAATGC would be TAAGCTTACG.
The two strands of DNA are complementary to each other. This means that the nucleotide bases in the DNA pair up with each other from the two strands.
In DNA, the base adenine (A) pairs with thymine (T), and the base cytosine (C) pairs with guanine (G). Therefore, the complementary strand will have opposite bases in the same order.
Hence, based on this base pairing we can conclude that when the sequence on one strand is ATTCGAATGC, the sequence on the other strand will be TAAGCTTACG.

According to the Kaplan-Meier plot, amplification of more than 10 copies of myc in neuroblastoma (see fig. 4-11b), decreases disease-free survival by more than 80% post-treatment. Explain two mechanisms that may contribute to gene amplification of myc?
Neuroblastoma is a type of cancer that develops in the nerve cells of the sympathetic nervous system. Amplification of more than 10 copies of the myc gene in neuroblastoma has been shown to decrease disease-free survival by more than 80% post-treatment, according to the Kaplan-Meier plot (see fig. 4-11b).
There are two main mechanisms that may contribute to gene amplification of myc:
Increased replication of the myc gene: One of the mechanisms that may contribute to gene amplification of myc is increased replication of the gene. This can occur due to mutations in the gene or in other genes that regulate its replication, leading to an increased number of copies of the myc gene in the cancer cells.Increased stability of the myc gene: Another mechanism that may contribute to gene amplification of myc is increased stability of the gene. This can occur due to mutations in the gene or in other genes that regulate its stability, leading to an increased number of copies of the myc gene in the cancer cells.Both of these mechanisms can contribute to the amplification of the myc gene in neuroblastoma, leading to decreased disease-free survival post-treatment.

Students will define the following terms associated with an action potential (resting membrane potential, threshold, depolarization, repolarization, hyperpolarization).Action potential.
An action potential is a process that allows for the transmission of electrical signals in neurons. It is made up of the resting membrane potential, threshold, depolarization, repolarization, and hyperpolarization.
The action potential is a process that occurs in nerve cells, or neurons, that allows for the transmission of electrical signals. It is made up of five key terms:
Resting membrane potential: This is the electrical potential, or voltage, of a neuron when it is not transmitting a signal. It is typically around -70 millivolts (mV).
Threshold: This is the minimum amount of stimulus required to trigger an action potential. It is typically around -55 mV.
Depolarization: This is the process of the neuron's membrane potential becoming less negative, typically due to the influx of sodium ions. It is a key step in the generation of an action potential.
Repolarization: This is the process of the neuron's membrane potential returning to its resting state, typically due to the efflux of potassium ions. It occurs after depolarization and is necessary for the neuron to be able to transmit another signal.
Hyperpolarization: This is the process of the neuron's membrane potential becoming more negative than its resting state, typically due to the efflux of potassium ions. It occurs after repolarization and helps to prevent the neuron from firing another action potential too soon.

Which direction will osmosis take place? 15. Please diagram the sodium/potassium pump and indicate how the sodium/potassium pump could result in an imbalance of ions on either side of the membrane. 16 For the following identify the signaling molecule, type of receptor, a protein activated or produced during the signal transduction pathway and the cellular response. Epinephrine binds to the Alpha-1-adrenergic receptor on sweat glands and liver cells. The binding of epinephrine to the receptor, activates G-protein and produces cAMP. Ultimately, the signaling within gland cells results in the secretion of sweat. In liver cells, the activated signaling pathway can result in the breakdown of glycogen producing glucose.
14. Penetration from solution B into solution A occurs. This is because solution A has a higher sugar content and a lower water content than solution B. Osmosis is the movement of water from areas of low solute concentration to areas of high solute concentration. Therefore, water moves from solution B, which has a lower solute concentration, to solution A, which has a higher solute concentration, trying to equalize the concentrations.
15. The sodium/potassium pump is a membrane protein that uses ATP to actively transport sodium ions out of the cell and potassium ions into the cell. This creates an ion imbalance on both sides of the membrane, with a higher concentration of sodium ions outside the cell and a higher concentration of potassium ions inside the cell. shows how it works.

It can be difficult to determine motility for a sulfur reduction positive organism in a SIM tube because the H2S produced in the medium can mask the motility test results. In order for the motility to be visible, the H2S must be eliminated from the medium, which is difficult to do.
In response to your lab mate's question, the agar may not be completely worthless as the SIM tubes may still be able to detect the cysteine desulfurase, thiosulfate reductase, and tryptophanase enzymes. However, too much agar may reduce the accuracy of these tests as the reaction may be slower and the detection of the enzymes may be more difficult.
In regards to the three species of bacteria in the SIM tubes, Bacterium 1 is expected to appear clear in color post-incubation, with no turbidity around the stab line, and a yellow color when Kovac's reagent is added. Bacterium 2 is expected to appear pink in color post-incubation, with turbidity around the stab line, and a pink color when Kovac's reagent is added.

An easier method is much appreciated for the exam.
The probability that at least 2 of their 4 children will have the blood type AB can be found by using Pascal's triangle. Pascal's triangle is a triangular array of numbers that shows the coefficients in the expansion of (a + b)^(n), where n is the row number.
For this problem, we can use the row corresponding to n = 4, which is 1 4 6 4 1. These numbers represent the coefficients in the expansion of (a + b)^4. In this case, a represents the probability of a child having the blood type AB, and b represents the probability of a child not having the blood type AB. So, the expansion of (a + b)^4 is:1(a^4) + 4(a^3)(b) + 6(a^2)(b^2) + 4(a)(b^3) + 1(b^4)We are interested in the probability that at least 2 of their 4 children will have the blood type AB, which is represented by the terms 6(a^2)(b^2) + 4(a)(b^3) + 1(b^4). Plugging in the given probabilities for a and b, we get:6(.25^2)(.75^2) + 4(.25)(.75^3) + 1(.75^4) = 0.3955So, the probability that at least 2 of their 4 children will have the blood type AB is 0.3955.Therefore, using Pascal's triangle, we can find the probability that at least 2 of Jane and Pascal's 4 children will have the blood type AB.Learn more about blood type inheritance here:https://brainly.com/question/27757703

Insulin resistance also increases risk. Insulin regulates blood sugar. Insulin resistance raises blood sugar, increasing the risk of metabolic syndrome.
In conclusion, the two risk factors of metabolic syndrome are an "apple" body type and insulin resistance.
Therefore, the correct answer is C. "Apple" body type and insulin resistance.

4. RAG-1 posesses all the following properties except a. a cell
cycle regulation domain b. a DNA cleavage domain c. a heptamer
binding domain d. a ligase domain e. a nanomer binding domain
RAG-1 possesses all of the following properties except for a (option d) ligase domain. The RAG-1 protein is essential for the process of V(D)J recombination, which is the process by which the genes that encode for the variable regions of antibodies and T cell receptors are rearranged to create a diverse repertoire of immune receptors.
RAG-1 has several domains that are important for its function in V(D)J recombination, including a cell cycle regulation domain, a DNA cleavage domain, a heptamer binding domain, and a nanomer binding domain. However, it does not have a ligase domain.
The ligase domain is responsible for joining the ends of DNA fragments together, and this function is carried out by a different protein called DNA ligase IV during V(D)J recombination. Therefore, the correct answer is d. a ligase domain.

What properties of water make it easier to walk on wet sand than dry sand?
Water has adhesive and cohesive properties that can make walking on wet sand easier than on dry sand.
When water is on the surface of wet sand, it sticks to the sand particles and creates a stronger bond than friction between the sole of the shoe and the dry sand. This means the shoe can grip wet sand more easily and have stronger traction.
In addition, the cohesion of the water helps hold the sand particles together, which can make the surface more solid and uniform than dry sand. In dry sand, the particles can slip and move more easily, which makes walking more difficult..

Enzymes.
Why is ATP important for cells and what is its structure? What is a coupled reaction and why is ATP involved in many coupled reactions?
Describe activation energy, the effects of enzymes and the mechanisms of enzyme action.
Activation energy is the minimum amount of energy required to initiate a chemical reaction.
Enzymes are biological catalysts that help to speed up chemical reactions by lowering the activation energy required for the reaction to occur.
The mechanisms of enzyme action involve the enzyme binding to the substrate, the molecule that the enzyme will act on, at the active site. This creates an enzyme-substrate complex, which allows the reaction to occur more efficiently. The enzyme then releases the product and is free to bind to another substrate molecule and repeat the process.
Enzymes can also be regulated by inhibitors, which prevent the enzyme from binding to the substrate, or activators, which increase the enzyme's activity. Overall, enzymes play a crucial role in many biological processes by speeding up chemical reactions and regulating their occurrence.

A tissue is a group of specialized cells, and there are different types of tissues. Adipose tissue is found in the hypodermis. The correct answer is ''hypodermis''
Adipose tissue is a type of connective tissue that is responsible for storing fat. It is composed of cells known as adipocytes, which store energy as fat. Adipose tissue is found in many places throughout the body, including the hypodermis, which is the layer of skin just below the surface.
This tissue acts as a natural insulator and cushion for the body. Adipose tissue can also be found in other areas of the body, including around the organs and in bone marrow. It serves an essential role in the body by storing excess energy in the form of fat, which can be used as a source of fuel when the body needs it.
In conclusion, the correct answer is ''hypodermis.''
