Question

(a) Expand DNA and RNA.
(b) In which part of the cell it is found? State its function.
(c) In which form is DNA present in (a) dividing cell (b) non-dividing cell?

Answer 1

a) Deoxyribonucliec acid,Ribonucliec acid
b)dna content biological and genetic intruction that controls the day to day function.dna is like a blueprint , which is necessary to construct other components of cell,like protein and RNA .
c)dna is formed in non dividing cell in chromatin fibre.dividin cell- chromosomes

Answer 2

Answer: A) DNA stands forr deoxyribonucleic acid and RNA stands for ribonucleic acid.

DNA is considered as the genetic material of living organisms. It is transcribed  to form RNA that is finally translated to form protein.

B) DNA is found in nucleus ( in eukaryotes) and cytoplasm ( in prokaryotes). In addition, it is also present in chloropast( in plants and algae) and mitochondria.

RNA is synthesised in nucleus and then it is transported to cytoplasm in case of eukaryotes whereas in prokaryotes, it is found in cytoplasm ( as they have no nucleus)  

C)  a) In dividing cell, DNA is present in highly condensed state in the form of chromosomes.

b) In non dividing cell, DNA is present in the relaxed or free form that is called chromatin.
