Question

What is meant by dna copying ?mention its importance in reproduction?

Answer 1

DNA (Deoxyribonucleic acid) is the genetic material found in the chromosomes, which are present in the nucleus of a cell. The DNA is the information site for making proteins and each specific type of protein leads to a specific type of body design.

Thus, it is the DNA molecule that determines the body design of an individual. Therefore, it can be concluded that it is the DNA that gets transferred from parents to offsprings and makes them look similar.

Answer 2

♤ DNA contains information for inheritance of characters from parents to the next-generation.

♤ As a result of DNA copying, blueprints of body design are produced which passes through parents to the offspring.

♤ Thus , DNA copying maintain the features in different generations of a species.

♤ DNA copying may creates variation which are useful for survival of species over a period of time.
