a. centromere
b. chromosomes
c. histone
d. chromatin

Answer 1

Answer:

D

Explanation:

Answer 2

Answer:

d. chromatin

Explanation:

Chromatin is a complex of DNA, RNA, and proteins that is present in the eukaryotic cell nucleus in the form of a long, spaghetti-like filament. Histones are the main proteins that make up the chromatins.

Chromatin is usually divided into two categories according to their condition: eucromatin and heterochromatin.

• Eucromatin: When the chromatin filaments are less condensed it means that it has active DNA, ie the cell is able to "read" the content of this genetic material.
• Heterochromatin: The filaments are condensed, coiled together in a tangle. In this case, the DNA is inactive because cells at that time are unable to encode the condensed genetic material.
