here are many genes that can affect coat color in ferrets. In particular, there is a gene that is necessary for melanocyte development (D). When this gene is mutant the ferrets are white, regardless of any of the other genes. A second gene affects the production of color in the melanocyte (R). Recessive mutations in this gene result in cream-colored animals, while the fully functional gene allows for animals of a darker color. A third gene causes longer chains of dopaquinone, and the dominant allele produces black animals (B), while the recessive allele produces brown animals. In animals that are black you can sometimes see a pattern of color that looks like stripes; this pattern is created by a gene (a) that affects deposition of color. Only black animals can be striped, and the striped allele is recessive. A brown animal, whose mother was cream colored, has babies.

Explanation:

The pathway that would be inhabited by avidin is lactate. Therefore, the correct answer is option A.

Biotin is the cofactor that's involved in the conversion of pyruvate to oxaloacetate with the help of the enzyme pyruvate carboxylase.

Lactate is formed when the rate of glycolysis is higher than the rate of oxidation. When that happens, the lactate is converted to form pyruvate with the help of the enzyme lactate dehydrogenase.

  Lactate + NAD+ -----> pyruvate + NADH + H+

The pyruvate is then converted to form oxaloacetate in the presence of biotin.

  Pyruvate + CO₂ + ATP + H₂O ----> Oxaloacetate + ADP + Pi + 2H+

Avidin binds tightly to the biotin. Thus avidin can inhibit the biosynthesis of glucose from lactate and its pathway.

Genetic engineering or recombinant DNA technology is a natural process, but it can be used in the laboratory to insert medically useful genes into bacterial cells that then produce a specific protein, like insulin or human growth hormone.

1. First, a gene of interest is isolated from a donor organism. This gene contains all the information necessary to produce the specific protein, such as insulin or human growth hormone.

2. Once the gene is isolated, it is inserted into a plasmid, a circular piece of DNA that is used to carry the gene into the target bacterial cell.

3. The plasmid is then inserted into the bacterial cell using a process called transformation. This is done by exposing the bacterial cells to a solution that contains the plasmid.

4. Once the plasmid has been successfully inserted into the bacterial cell, it is replicated along with the bacterial genome. As the cell continues to replicate, the gene of interest is copied into all of the daughter cells.

5. The gene of interest is then expressed, or activated, in the host cell. This causes the cell to produce the desired protein, such as insulin or human growth hormone.

6. Finally, the host cell is harvested and the protein is extracted from the cell. This process is called gene cloning and is used to mass-produce the desired protein in a controlled environment.

Autonomic neurons are a type of nerve cell that regulates the activity of the body's involuntary or "visceral" muscles and organs. The Autonomic Nervous System “ANS” is the part of the nervous system that controls these involuntary functions.

The sympathetic nervous system is responsible for activating the body's "fight or flight" response during times of stress or danger. It does this by releasing the hormone adrenaline and increasing heart rate, blood pressure and breathing.

The sympathetic nervous system also stimulates the production of glucose by the liver and the breakdown of fat in adipose tissue, providing the body with energy during periods of high activity.

The parasympathetic nervous system, on the other hand, acts to balance the sympathetic nervous system, promoting relaxation and calmness. It does this by slowing the heart rate, lowering blood pressure, and increasing the digestion and absorption of nutrients.

Autonomic nerve cells are activated by signals from the brain and spinal cord and can also be influenced by hormones and other chemicals in the body. They use chemical signals called neurotransmitters to communicate with the muscles they control and communicate with organs.
