What color would a dog's fur be if its genes are aabb? 31 Il O a​

Answers

Answer 1

Recessive epistasis occurs when the recessive allele of one gene is epistatic over the other gene. The resulting phenotypic ratio is 9:3:4. In the exposed example, the phenotype of the aabb dog is yellow. Option A.

What is epistasis?

Epistasis means interruption and refers to interactions between genes located in different loci in the same chromosome.

An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.

Epistasis might be either dominant or recessive,

When the epistatic gene is dominant, the interaction is known as dominant epistasis.

The phenotypic ratio resulting from dominant epistasis is 12:3:1.

When the epistatic gene is recessive, the interaction is known as recessive epistasis.

The phenotypic ratio is 9:3:4.

The exposed situation is an example of recessive epistasis, in which two diallelic genes affect the dog's fur color,

B is a dominant allele that codes for black color.b is a recessive allele that codes for brown color.

A is the dominant allele that allows the expression of pigment.a is the recessive allele that that inhibits pigment expression. In this case, fur is yellow.

The presence of at least one A allele is enough to express black (BB or Bb) or brown (bb) color. The absence of the A allele inhibits pigment expression.

The possible genotypes and phenotypes are,

AABB, AaBB, AaBb, AABb ⇒ Black AAbb, Aabb  ⇒ BrownaaBB, aaBb, aabb ⇒ Yellow

As we can see in the Punnett square, the phenotypic ratios are 9:3:4

9/16 black dogs3/16 brown dogs4/16 yellow dogs.

So the genotype aabb expresses yellow color. The genotype aa inhibits color expression, so the dog's fur is yellow. Option A is correct.

Use complete sentences to explain how important the shape of an enzyme is.
Use the words: active site and denatured​

Answers

Answer:

The shape of an enzyme is important because it determines the enzyme's function. The active site is the specific area on the enzyme where chemical reactions occur. The active site is specific to the type of substrate that the enzyme is designed to work with, and its shape must match the shape of the substrate in order to facilitate a chemical reaction. If the shape of the enzyme changes, the active site may no longer match the shape of the substrate, and the enzyme will no longer be able to function properly. This process is known as denaturation, and it occurs when the enzyme's shape is altered due to changes in temperature, pH, or other environmental conditions. When an enzyme is denatured, it becomes inactive and is no longer able to catalyze chemical reactions. Therefore, the shape of an enzyme is critical to its function, and any changes to its shape can significantly impact its ability to carry out chemical reactions.

how do papillary muscles prevent atrioventricular valve cusps from everting (swinging upward) into the atria?

Answers

Atrioventricular valve cusps are prevented from everting (swinging upward into the atria) by contracting papillary muscles.

The chordae tendineae are pulled when the papillary muscles contract, which prevents the atrioventricular valves' cusps from opening and allowing blood to return to the atria. Thin, fibrous tissue strands known as chordae tendineae join the two atrioventricular valves—the mitral valve and the tricuspid valve—to the ventricles. The cusps or flaps of each valve are held in place by the chordae tendineae and papillary muscle. Pressure gradients across the valves cause the mitral and tricuspid valve cusps to close as the ventricles contract. Blood may leak backward or vomit if the chordae tendineae are not sufficiently taut, so the cusps can shut properly. The mitral valve cusps, in this instance, are prolapsing or failing to seal completely. From the ventricle, blood is dripping back into the left atrium.

Hence, papillary muscle with chordae tendineae holds cusp of valve.

the biggest problem with the shotgun technique is its tendency to underestimate the size of the genome. which of the following might best account for this? a) skipping some of the clones to be sequenced b) missing some of the overlapping regions of the clones c) counting some of the overlapping regions of the clones twice d) having some of the clones die during the experiment and therefore not be represented

Answers

Option D. is correct, The shotgun method's major flaw is its propensity to overestimate the size of the genome.

The DNA sequence of an organism's genome can be ascertained in a lab setting using a process called shotgun sequencing. The process entails randomly dividing the genome into tiny DNA fragments that are then individually sequenced. First proposed in 1979, whole genome shotgun sequencing for small (4000 to 7000 base-pair) genomes. The genome of the cauliflower mosaic virus was the first one to be shotgun sequenced and was made public in 1981. Hierarchical shotgun sequencing, which requires the first generation of a low-resolution map of the genome, is slower than whole-genome shotgun sequencing but uses fewer computer methods.

what is generally the starting material for whole-genome shotgun sequencing of genomic dna? see section 16.1

Answers

The starting material for whole-genome shotgun sequencing of genomic DNA is overlapping fragments of genomic DNA.

The DNA sequence of an organism's genome can be ascertained in a lab using shotgun sequencing. The process entails randomly dividing the genome into tiny DNA fragments that are then individually sequenced. To reconstruct the genome, a computer program searches for overlaps in the DNA sequences and uses those overlaps to put the fragments back together in the right order.

Shotgun sequencing involves randomly slicing the genome into small, sequencing-ready pieces (1 to 2 kbp in length). After being ligated into an appropriate vector, the fragments are partially sequenced. Each fragment can yield 400–500 bp of sequence in a single sequencing run.

Hence, small fragments are sequenced and organized with computer.

Suppose that there was an enzyme that cuts bonds between deoxyribose and phosphate groups. what would this enzyme do to a dna molecule?

Answers

The enzyme that cuts bonds between deoxyribose and phosphate groups would make cuts in the "backbone" of each strand of a DNA molecule.

Bacteria include restriction enzymes (and other prokaryotes). They identify and attach to particular DNA sequences known as restriction sites. Only one or a few restriction sites are recognised by each restriction enzyme. A restriction enzyme will create a double-stranded cut in the DNA molecule once it locates its target sequence. The cut typically occurs in a neat, regular pattern at or near the restriction point.

in the process of glycolysis, four atp molecules are synthesized from four adp molecules. why does glycolysis not yield four molecules of atp?

Answers

The net benefit of glycolysis is only two ATP because the two ATP molecules are consumed in  initial part of glycolysis, even if the four ATP molecules are created in  second half.

One glucose molecule initiates glycolysis, which culminates with two pyruvate (pyruvic acid) molecules, four ATP molecules overall, and two NADH molecules. The cell has the net gain of two ATP molecules and two NADH molecules for usage since the two ATP molecules were required in the first half of the route to prepare  six-carbon ring for cleavage. Only two ATP molecules will be produced from a molecule of glucose if the organism is unable to further catabolize  pyruvate molecules (through the Krebs cycle or citric acid cycle). Pyruvate kinase, the enzyme that catalyzes the production of pyruvate, must be present in sufficient amounts for the final stage of glycolysis to take place.

The entire glycolysis pathway will in this case ,the full glycolysis pathway will continue to function, but the second half will only produce two ATP molecules (instead of the usual four ATP molecules). As a result, the rate-limiting enzyme for glycolysis is pyruvate kinase.

Answers

Answer:

MSUD stands for Maple Syrup Urine Disease. It is very rare, it occurs in about 1 of every 185,000 births worldwide. A child is born with MSUD when both parents are carriers of three specific gene mutations (changes) – one copy from each parent. These three specific amino acids are leucine, isoleucine and valine.

trace the movement of a hormone from the organ that produces it to its target binding site (organ or tissue). how does this hormone get from the organ/gland that produces it to its binding site

Answers

Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell's activities.

The endocrine organs, which produce chemicals—the hormone—into the extracellular fluid, are responsible for sending these messages. Throughout the body, hormones are largely delivered via the circulation, where they connect to receptors on target cells to produce a specific reaction. Because it has the hormone's receptors, a target cell reacts to the hormone. In other words, a cell is a target cell for a hormone if it has functional receptors for that hormone, and a cell cannot be directly impacted by a hormone if it does not have a functioning receptor. Blood, which is pumped throughout the circulatory system, carries hormones throughout the body. Hormones have the power to control activity in tissues and organs that are not located near the glands that produce them.
