During the time of normal cell activity, dna exists in a loose, spaghetti-like form called
a. centromere
b. chromosomes
c. histone
d. chromatin

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.
