A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

One of the first Mendelian traits identified in humans was a dominant condition known as brachydactyly. This gene causes an abno
kvv77 [185]

Answer:

The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.

Explanation:

Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.

How do the sequence and composition of amino acids in a protein influence how a protein folds up
Fynjy0 [20]

Answer:

See the explanation below, please.

Explanation:

The amino acid sequence of a protein will determine the interactions inside and with the environment (that is, it will influence the conformations that are adopted at physiological temperature: the degrees of freedom). Example: the proline amino acid (Pro) has a cyclic structure, which implies a limitation in the random movement of the polypeptide chain.

In proteins, the primary structure determines the sequence of the amino acid sequence of the polypeptide chain (amount of amino acids present and their order by means of peptide bonds).
