1. What is the importance of DNA copying in reproduction?2. Why is variation beneficial to the species but not necessarilyfor the individual? |
|
Answer» 1ans:DNA(Deoxyribonuclei acid) is the genetic material found in the chromosomes,which are present in the nucleus of a cell.the DNA is the informative site for making proteins and each specific type of protein leads to a specific type of body designs. 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. 2.Variationsarebeneficialfor the survival of thespecies. Populations of organisms fill well-defined places, or niches, in the ecosystem, using their ability to reproduce. However, niches can change because of reasons beyond the control of the organisms and could even wipe out the entire population. 1 ans:DNA copying in reproduction is important for maintenance of body design and features. Moreover, DNA copying leads to variations. Variation is useful for survival of species. |
