Answer:
Correct Answer: A
Solution:
DNA is the genetic material in most of living organism except the plant viruses and some bacteriophages.
It is the only molecule which can replicate itself or can form its own carbon copy.
The phenomenon is called molecular reproduction.
All the information required for growth, differentiation, running cellular machinery and reproduction is contained in DNA molecules.
These genetic information of DNA are like the blue print.
During cell division (which involve DNA replication, the daughter cell receive the same blue print or genetic material as in the parental cell.)
