Answer:
d. chromatin
Step-by-step 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.
