Understanding the structural and molecular interactions that induce shape and function for a protein has been an obstacle for some of your students. You decide to plan a lesson to introduce them to the basic amino acid structure and then use that concept to introduce the different levels of protein structure. To reinforce your lesson on amino acids, you need to aid the students in understanding that most naturally occurring amino acids have a shared base structure. Each amino acid has an amine group, an alpha-carbon (or central carbon), an R-side group, and a carboxyl group. The R-side group is what gives each amino acid its distinctive characteristics--for example, whether the amino acid will be acidic or basic, hydrophilic or hydrophobic, or charged.
Choose the statement that does NOT pertain to amino acids.
a. All amino acids must contain a nitrogen-based molecule and a carboxylic acid.
b. Amino acids always contain a sulfur atom in their R-side group.
c. The groups composing an amino acid are located around a central alpha-carbon.
d. The R-side group will determine the overall chemical properties of an individual amino acid.
Answer:
b. Amino acids always contain a sulfur atom in their R-side group.
Explanation:
Amino acids are monomeric units of protein molecules. This means that a protein molecule is made up of a chain of amino acids. As stated in this question, an amino acid is structurally made up of a central carbon atom called α carbon, an amine group (-NH2), a carboxylic acid group (-COOH), and a R-group side chain, which distinguishes each amino acid from one another.
Based on this question, all amino acids must possess the following characteristics:
- must contain a nitrogen-based molecule (amine group) and a carboxylic acid.
- The groups i.e amine, carboxylic acid and R chain are located around a central alpha-carbon.
- The R-side group will determine the overall chemical properties of an individual amino acid i.e whether acidic, basic, hydrophilic etc.
However, considering the fact that the R side chain of individual amino acids are different from one another, not all amino acids will contain a sulfur atom in their R-side group. Note that, Methionine and cysteine are the two common sulfur-containing amino acids.

You decide to conduct a genetic analysis of these mutant lines by crossing each with a pure-breeding wild-type line. The numbers in the F2 indicate the number of progeny in each phenotypic class. Three crosses between pure lines. Cross 1 between plants with twisted and wild-type leaves results in plants with twisted leaves. An F1 F1 cross results in 53 plants with twisted leaves and 18 wild-type plants. Cross 2 between plants with forked and wild-type leaves results in plants with forked leaves. An F1 F1 cross results in 49 forked and 16 wild-type plants. Cross 3 between plants with pale and wild-type leaves results in plants with leaves of intermediate color. An F1 F1 cross results in 34 plants with intermediate leaves, 17 wild-type plants, and 16 plants with pale leaves. From these results, determine the relationship between the mutant allele and its corresponding wild-type allele in each line. Label each mutant line with the best statement from the list below. Labels may be used once, more than once, or not at all
Complete question:
You will find the complete question in the attached files
Answer:
For the twist trait: The mutant allele is dominant to its corresponding wild-type allele For the forked trait: the mutant allele is dominant to its corresponding wild-type allele For the pale trait: The mutant allele is neither dominant nor completely recessive to its corresponding wild-type alleleExplanation:
Cross 1: twisted x wild-type ----> Pure linesParentals) TT x tt
F1) twisted leaves, Tt. ---> Heterozygous
Parentals) Tt x Tt
Punnett square) T t
T TT Tt
t Tt tt
F2) 53 twisted, 18 wild-type
Total number of individuals in the F2 = 53 + 18 = 71
71 plants -------- 100% of the F2
53 twisted------X = 75% TT + Tt
18 wild-type----X = 25% tt
Phenotypic ratio 3:1
The phenotype of the F1 and F2 progeny tells us that the twist trait is dominant over the wild type. The fact that the whole F1 generation was twisted is enough information to assume that the wild type is recessive and the twisted is dominant. Also, the phenotypic ratio of the F2 corroborates this assumption.
Cross 2: forked x wild-type ---> Pure LinesParentals) FF x ff
F1) 100% forked, Ff----> Heterozygous
Parentals) Ff x Ff
Punnett square) F f
F FF Ff
f Ff ff
F2) 49 forked and 16 wild-type plants
Total number of individuals in the F2 = 49 + 16 = 65
65 plants -------- 100% of the F2
49 forked------X = 75% FF + Ff
16 wild-type----X = 25% ff
Phenotypic ratio 3:1
The phenotype of the F1 and F2 progeny tells us that the twist trait is dominant over the wild type. The fact that the whole F1 generation was forked is enough information to assume that the wild type is recessive and the forked is dominant. Also, the phenotypic ratio of the F2 corroborates this assumption.
Cross 3: pale x wild-type ---> Pure linesParentals) PP x pp
F1) 100% Pp, intermediate color.
Parentals) Pp x Pp
Punnett square) P p
P PP Pp
p Pp pp
F2) 34 intermediate, 17 wild-types, and 16 pale.
Total number of individuals in the F2 = 34 + 17 + 16 = 67
67 plants -------------- 100% of the F2
34 intermediate ------X = 51% Pp
17 wild-type-------------X = 25% pp
16 pale -------------------X = 24% PP
Phenotypic ratio 1:2:1
The phenotype of the F1 and F2 progeny tells us that the pale trait is not dominant neither recessive to the wild type. The fact that the whole F1 generation was intermediate is enough information to assume that none of the traits dominates over the other. This is a case of incomplete dominance. The heterozygous individual express an intermediate phenotype between both the parentals´ one. Also, the phenotypic ratio of the F2 corroborates this assumption.
What does the mnemonic device "Did King Philip Come Over For Good Spaghetti" mean, in terms of Taxonomy and Classification?
Answer:
See the answer below
Explanation:
The mnemonic is used to represent the major taxonomic categories used in classifying living organisms. Each of the words in the sentence (except 'Did') represents the categories as follows:
King - Kingdom
Philip - Phylum
Come - Class
Over - Order
For - Family
Good - Genus
Spaghetti - Species
The kingdom represents the highest category of classifying living organisms. Each organism has to belong to one of the 5 major kingdoms - monera, protista, fungi, plant, or animal. Phylum comes after the kingdom, followed by class, order, family, genus, and species. The lower the category, the lower and more similar the organisms they contain.

Describe an example of how gene expression is regulated.
Answer:
Gene regulation is how a cell controls which genes, out of the many genes in its genome, are expressed. These different patterns of gene expression cause your various cell types to have different sets of proteins, making each cell type uniquely specialized to do its own job.
Explanation:
An example of gene expression is the differential expression of the genes in human cells. All types of human cells contain the same DNA however they have very different structures and functions to perform. Liver cells and neurons present in the brain contain the same DNA yet they are very different in structure and function.
What is Gene expression?Gene expression is the process through which information from a gene is used in the synthesis of a functional gene product which enables it to produce end products, such as proteins or non-coding RNA molecules, and ultimately affect a phenotype, as the final effect of their expression.

How are functional MRI machines being used to determine the function of different parts of the brain?
Answer:
Magnetic resonance imaging (MRI) is a technology that produces 3D images in order to assess brain activity, which is used in the diagnosis, monitoring and treatment of diseases
Explanation:
Magnetic Resonance Imaging (MRI) is a non-invasive method that generates three-dimensional (3D) images which are used for diagnostics and disease monitoring. MRI is useful to distinguish between white and grey matter in the brain, and thereby this technique can be used for the diagnosis of tumors and aneurysms which are caused by weakness in the arterial walls. Moreover, MRI is also useful to analyze the relationship between regions of the brain and cognitive processes by monitoring the neurological-psychophysiological status of an individual.

Electrical impulses travel down Bundle of His/Purkinje fibres resulting in which stage of the cardiac cycle?
a.Sino atrial(SA) contraction
b.Diastole
c.Ventricular contraction
d.Atrial contraction
Answer:
The correct answer is c.
Explanation:
The cardiac impulse spreads through a bundle of fibers that is a bridge between the atrioventricular node and the ventricular branches, called the bundle of His, supplied by branches of the right coronary artery and the anterior descending artery. The bundle of His is divided into 4 branches: the right and left branches and the latter is divided into the anterior left fascicle and the posterior left fascicle, from where the electrical impulse is distributed to the ventricles through a network of fibers that cause contraction ventricular cells called Purkinje fibers, triggering ventricular contraction. The AV bundle conducts the impulse from the atria to the ventricles. The right and left branches of the Purkinje fibers conduct the cardiac stimulus to all parts of the ventricles. Purkinje fibers or tissue are located in the inner ventricular walls of the heart, below the endocardium. These fibers are specialized myocardial fibers that conduct an electrical stimulus or impulse that intervenes in the heart's nerve impulse causing it to contract in a coordinated manner.

Given that the function of egg yolk is to nourish and support the developing chick, complete the explanation of why egg yolks are so high in fat, protein, and cholesterol.
Answer:
Chick with in the egg depend for all its energy and food requirement on the egg yolk , therefore egg yolk is rich in fat, protein, and cholesterol.
Explanation:
Before the egg breaks and the chick comes out, few days nourishment for chicks is required. Hence, the egg yolk needs to be nutritious as new developing chick (with in the egg) rely for essential nutrients (required for growth) on the egg yolk. Chick require energy from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers
