Question

Discuss what is the importance of DNA copying in reproduction?

Answer 1

Hint: DNA contains the blueprints for how to make the proteins and other molecules that make the cell run. The cells would not be able to make molecules without it and they would not be able to survive, and thus would die. DNA determines the body's design of an individual. DNA copying is important for reproduction as a mechanism is necessary for reproduction as the copying of DNA helps in the transfer of information or characters from parents to offspring.

Complete answer:
The replication of a cell is the process of going from one cell to two cells. As we know the original single-cell had only one set of DNA it needs to copy so that both resulting cells have the DNA they need to survive. The reproduction of multicellular organisms is essentially a lot of cell replications, followed by differentiation of those cells. The copying of DNA during reproduction is important because the replication of DNA ensures that each daughter cell formed at the end of cell division, receives an equal amount of DNA. The daughter cells won't receive all necessary genes if by chance DNA won't be copied. There may be an absence of important proteins that are encoded by DNA if DNA won't be replicated. It codes for proteins required by an individual. The correct proteins will not be formed if DNA is not copied during reproduction, and then the structure of the individual will be entirely different and evolution can be led by this copying of DNA as a result of recombination. Transfer of genetic material from one generation to another makes the organisms have similar functions. The stability of the population is maintained. The offspring might face some serious abnormalities or might not even develop if DNA is not copied properly. For example, the parent cell will be able to produce two daughter cells with the same number of chromosomes or DNA as that of the parent cell only after producing another copy of its DNA. During reproduction, the DNA in the nucleus replicates itself to produce another set of chromosomes or DNA.

Note: The process of DNA replication is very crucial; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA. The cell can divide into two cells once the DNA in a cell is replicated and each of which has an identical copy of the original DNA.
