Which label best represents the area marked Y? chromosome protein gene DNA

The label representing the area marked Y is male chromosome.

Explanation:

The role of protein is to control the gene transcription in the preliminary stages of protein synthesis.

DNA in chromosomes are associated with proteins and so they are called chromatin.

Chromosomes are structures of the cells that contains person's genes. The genes are found in chromosomes. DNA is formed by a sugar, a phosphate group and four nitrogen bases they are Adenine(A), Thymine (T), Cytosine (C) and Guanine (G).

The genetic code is a set of rules where encoded genetic material information is translated into proteins by living cells. The labels X and Y represents the male and female chromosomes.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
