Question

Give one key difference between chromatin and chromosome.
A) Chromatin is the DNA and proteins that makeup chromosomes.
B) Chromosomes are the DNA and proteins that makeup chromatin.
C) Chromosomes are the DNA and sugar that makeup chromatin.
D) Chromosomes are the RNA and proteins that makeup chromatin.

Answer 1

Hint: Chromatin and chromosome are two types of structures of the DNA double helix appearing in different stages of the cell. For existence the cell's genetic information has been stored by the DNA double strand which should be packed into the eukaryotic nucleus. The usual form of the packaged DNA in the cell is known as Chromatin. Chromosomes appear at the metaphase of the nuclear division.

Complete Answer:
The unravelled condensed structure of DNA has been consisted by the chromatin for the purpose of packaging into the nucleus whereas the highest condensed structure of the DNA double helix has been consisted by the chromosome for the proper separation of the genetic material between daughter cells.

Chromatin makes up eukaryotic chromosomes and it is the complex of DNA and proteins. By proteins at the centromere and, sometimes, along the arms the two copies of a duplicated chromosome attached to each other which is known as chromatid. One chromosome joined two sister chromatids to make up.

Hence, The option C: Chromosomes are the DNA and sugar that makeup chromatin is the correct answer.

Note: Chromatin is a substance within a chromosome consisting of DNA and protein. Chromatin is a building block of all the chromosomes and is a strand of DNA wrapped around a protein. The structure in which DNA is stored in D is known as chromosome.
