What form is DNA is in during Interphase?
A
Chromatin
B
Replicated Chromosome
C
Unreplicated Chromosome
D
Chromatids
Explanation: 

Detailed explanation-1: -Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration.

Detailed explanation-2: -During interphase the DNA strands are uncoiled (uncondensed) in the nucleus. This uncondensed genetic material is called chromatin; thus an uncondensed chromosome can be called chromatin.

Detailed explanation-3: -Chromatin Chromatin refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms. Many of the proteins-namely, histones-package the massive amount of DNA in a genome into a highly compact form that can fit in the cell nucleus.
