Question

Explain the difference between chromosomes, chromatids and chromatin. (3-4 sentences)

Answer 1

Chromatin is the unbound form of the genetic material and the primary state of DNA, RNA, and protein in the nucleus of the cell. Chromosomes are the condensed form of chromatin. Chromatin becomes chromosome in the Prophase of mitosis and Prophase -I and Prophase- II of meiosis. Chromosomes are made up of chromatids which are internally made up of chromatin.

Chromatin is made up of condensed DNA. Chromatid is made up of maximum condensed chromatin. Chromosome is made up of chromatids.

Chromatin is the DNA and the protein that make up the chromosome. Chromosomes are the separate pieces of DNA in the cell. Chromatids are the equivalent pieces of DNA that are held together by a centromere and are pulled apart during cell division to make new identical chromosomes.

Answer 2

CHROMATIN : It can be simply referred to as genetic material in loose or normal form. It can be DNA or RNA inside the plant or animal cell's nucleus.

2. CHROMOSOME : When the chromatin material is condensed prior to the cell division and get highly organized form that can be visible in form of proper structures have two chromatids, they are called chromosomes.

The process of formation of chromosomes from chromatin occurs mainly in prophase of Mitosis or Prophase II or Prophase I of Meiosis.

3. CHROMATID : Chromatid is also referred to as sister chhromatids since there are two chromatids present in one chromosome that are almost similar. Chromatids can be considered as arms of chromosomes which are attached at a point centromere (please see the image for better understanding).
