In human, Oogenesis in comparison to spermatogenesis is different in that Oogenesis does not complete meiosis until after fertilization, but spermatogenesis is complete before the sperm leave the body. Oogenesis is the process by which the female gametes, or ova are created in the female's ovary. Spermatogenesis is the process in which males synthesis sperms. The two process are part of gametogenesis which involves meiosis type of cell division, in which a diploid cell divides into four haploid daughter cells.
<span>The Answer is "R" group.
Amino acids are organic compounds and have two carbon bonds. The three parts of an amino acid are the amino group, the carboxyl group, and the R group. In amino acids, alpha carbon is bonded to hydrogen atom and the other groups. That R group is different in amino acids and shows how the protein monomers are different from each other. </span>
