The genetic information from DNA is transcribed into mRNA which is translated into polypeptide. The genetic information of mRNA is translated into polypeptide.

Sexual reproduction requires cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction. Thus, the correct option is D.
Sexual reproduction involves the production of new organisms through the combination of genetic information of two individuals which are of different sexes. In most of the species, the genetic information is being carried on by the chromosomes in the nucleus of reproductive cells which are known as germ cells or gametes, which then undergo fertilization and fuse to form a diploid zygote.
Gametes are produced through meiosis because these are haploid. Thus, sexual reproduction required cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction.
Therefore, the correct option is D.

D. Meiosis because babies or humans are made of a combination of our parent’s genes. Meiosis is mitosis times 2. So you get more pairs that are different. Mitosis produces identical offsprings.
