Question

Why DNA copying is very important? Explain. (5 marks)

Answer 1

IMPORTANCEOFDNACOPYING:

• DNApresent in the nucleus contains all the information for the inheritance of feature from parents to offsprings.
• DNA codes for all the proteins required by an individual.
• Proteins control all the functions and the structure of an individual.
• If DNA is not copied during reproduction , correct proteins will not be formed and the structure and functions of the individual will be entirely different.
• Errors in dna copying lead to evolution
• It helps in proper survival of organism by similar copying
• It makes the organism look similar to each other
• Organisms of the same species look similar because their body designs are similar. DNA contains the information necessary for the inheritance of features. Therefore consistancy of DNA copying is important for the maintenance of body design features that allow the organism to use that particular niche. It is necesaary to maintain the stability of populations of species.
