Explain why mutations that replace S/T/N residues with A/L/W residues in the N-terminal region of transmembrane proteins that function as cell surface receptors could significantly disrupt that utility of these proteins as receptors.

Answers

Answer 1

Answer:

Serine (S), Threonine (T) and Asparagine (N) are primary binding sites of carbohydrates, and thereby they are required to form glycoproteins (i.e., glycosylation products)

Explanation:

A transmembrane protein (TP) is a particular type of protein that crosses the cell membrane in order to enable the movement of ions and molecules. Transmembrane proteins are divided into alpha-helical and beta-barrel proteins. The N-terminal region of transmembrane glycoproteins can be required for N-linked glycosylation, which is an enzymatic mechanism capable of attaching oligosaccharides to proteins in order to form glycoproteins (glycans). N-linked glycosylation is a posttranslational protein modification that has distinct functions depending on the cell type and the protein region involved in such modification. For example, in the surface of immune cells, the N-linked glycans are capable of dictating the migration pattern of these cells.

Identify two structural features of purines and pyrimidines. Purines contain only three ring nitrogen atoms. contain only two ring nitrogen atoms. contain four ring nitrogen atoms. contain two heterocyclic rings. contain one heterocyclic ring.

Answers

Answer:

1) Purines contain only four ring nitrogen atoms while Pyrimidines contain only two nitrogen ring atoms

2) Purines contain two heterocyclic rings while Pyrimidines contain one heterocyclic ring

Explanation:

Purines and Pyrimidines are two classes of nitrogenous bases that make up nucleic acids. They are both heterocyclic aromatic compounds which contains nitrogen atoms in their structure. Although, they are similar but have distinct features namely:

Purines are ring molecules which consists of four (4) nitrogen atoms in their aromatic structure. They are structures with two heterocyclic rings consisting of five (5) carbon and four (4) nitrogen atoms. Adenine and Guanine are the purines in nature.

On the other hand, Pyrimidines are another ring molecules consisting of two (2) nitrogen atoms in their aromatic structure. Their only ring i.e. 1, is also heterocyclic in nature and contains four (4) carbon and two (2) nitrogen atoms. Cytosine, Thymine and Uracil are the pyrimidines.

Which is the pair of the enzyme activities most significantly affected by glucagon- and insulin-dependent phosphorylation and dephosphorylation of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFKFB)?
a. hexokinas ::::: glucose-6-phosphatase
b. phosphofructokinase ::::: Fructose-1,6-bisphosphatase
c. pyruvate kinase :::::: pyruvate carboxylase
d. glycogen synthase ::::: glycogen phosphorylase
e. None of these

Answers

Answer:

b. Phosphofructokinase;  Fructose-1,6-bisphosphatase

Explanation:

Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.

Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).

It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .

It is formed by phosphorylation of fructose-6-phosphate catalyzed by  phosphofructokinase-2 and is broken down by fructose-2,6-bisphosphatase which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).

Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.

Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.

Autosomal dominant and recessive: Autosomal dominant states a pattern of inheritance in which an individual carries one normal gene and one copy of a mutant gene while autosomal recessive states a pattern of inheritance in which an individual have two copies of the mutant gene.

Incomplete dominance:  Incomplete dominance states a heterozygous condition in which both the alleles present are partially expressed and produces intermediate phenotype.

Codominance: In codominance and individuals receive alleles, if both the alleles are different including dominant and recessive, dominant allele will be expressed while recessive will be masked.

Multiple alleles: organisms with multiple alleles exist with two copies of every gene present in a population with variation in genes.

Sex linked gene: In humans and some other organisms, sex linked genes are influenced by genes on the X chromosome. for example: If a gene is present on the X chromosome only and not the Y chromosome.

Without crossing over, the independent assortment of the homologous chromosomes in a cell with these chromosomes will produce two different genotypes. Which are they

Answers

Answer and Explanation:

Crossing over occurs during meiosis. When homologous chromosomes are aligned and they stick together by the chiasma point.  At this point, the homologous chromosomes chains break and get recombined with the broken portion of its homologous. The result is that one of the progenitor´s chromosome will have a portion of the other progenitor´s chromosome, and vice-versa.  

If crossing-over does not occur, the independent assortment of the homologous chromosomes in a cell will produce two different genotypes that equals the ones of the progenitors. So, there will be two genotypes, one of them equals the female´s genotype and the other is like the male´s genotype.

Explain why chemogenetic based methods of regulating cellular signaling result in poor temporal control of biochemical pathways relative to optogenetic based methods.

Answers

Answer:

They use different detecting methods to assess neuronal circuits

Explanation:

Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.

help asap true or false Uranus orbits the Sun at less than 40% of the speed of Venus.

Answers

Answer:

True

Explanation:

The attached image shows a table that displays the eight (8) planets, their respective average distance from the sun and their respective orbital speeds.

The question only relates the orbital speed of planets Uranus and Venus, which is 7km/s and 35km/s respectively.

40% of the orbital speed of planet Venus is:

= 40/100 × 35

= 0.4 × 35

= 14

According to the table in the image, Uranus orbits around the sun at a speed of 7km/s, which is lesser than 40% of Venus's orbital speed (14km/s).

Therefore, it is TRUE that Uranus orbits the sun at less than 40% of the orbital speed of Venus.
