HEEL I need this answer for my benchmarkkk Coat color in a particular variety of rabbits is controlled by multiple alleles. There are four possible alleles that each express a different phenotype. The allele for dark gray coat color (C) is dominant to all other alleles. The allele for chinchilla coat color (cch) is dominant to both the allele for Himalayan coat color (ch) and the allele for white coat color (ca). The allele for white coat color (ca) is recessive to all other alleles.

Part A: Predict the phenotype that will be expressed by a rabbit that has an allele for Himalayan coat color and an allele for white coat color (chca).

Part B: Suppose a solid white rabbit (caca) mates with a rabbit that has an allele for dark gray coat color and an allele for Himalayan coat color (Cch). Predict the percentage of each possible phenotype that will result from this cross. In your answer, be sure to explain the reasoning behind your prediction.

Part C: Describe how traits controlled by multiple alleles are different from polygenic traits.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
