Uncoiled stringy DNA is called
A
DNA
B
meiosis
C
chromatin
D
both a and b
Explanation: 

Detailed explanation-1: -During this phase, the DNA is uncoiled and called chromatin.

Detailed explanation-2: -What is uncoiled, stringy DNA called? It is called chromatin. How many pieces of chromatin does a human diploid cell have? Human diploid cells have 46 pieces of chromatin.

Detailed explanation-3: -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.

Detailed explanation-4: -Telophase. During telophase, the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells.

Detailed explanation-5: -The chromosome consists of a single chromatid and is decondensed (long and string-like). The DNA is copied. The chromosome now consists of two sister chromatids, which are connected by proteins called cohesins.
