In the year 1952, two scientists, Hershey and Chase conducted a series of experiments that helped to establish the fact that DNA is a genetic material. The DNA is located inside the nucleus of living cells in form of chromosomes and its the determinant of traits that are found in living organisms. During protein synthesis, the information in the DNA molecule is encoded into an RNA molecule and this is used in the production of protein, thus, DNA actually directs all the happen in the living cells.
Why is internal Fertilisation important to animals?
Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young.
