Which of the following shows a relation between chromatin and chromosome? (1m) i. Each chromosome consists of two similar halves called chromatin. ii. Chromatin is thin thread-like structures made of DNA and protein which condenses during cell division to form thicker rod-like structures called chromosomes. iii. When the cell is about to divide, the chromosome gets organised into chromatin. iv. Chromosomes and chromatin have no role in the inheritance of features from parents to the next generation.
Answers
Answer:
(ii)
Explanation:
Answer is (ii) Chromatin condenses to form chromosomes during cell division
Answer:
In the nucleus, the DNA is a pack of special proteins known as histones. This helps in the formation of a complex called chromatin. The chromatin goes through further condensation to form the chromosome. A human body has 23 pairs of chromosomes. Learn the difference between chromatin and chromosomes here.
The chromatin is a lower order of DNA organization, on the other side chromosomes are the higher order of DNA organization. The genetic content in an organism is counted as the pairs of chromosomes present. The structure of Chromatin is the composition of the nucleosomes-a complex of DNA and proteins known as histones. The diameter of the chromatin fiber is 10 nm. Chromosomes are a higher order of DNA organization, where DNA is condensed at least by 10,000 times onto itself.
