WebSperm cells are gametes (sex cells) that are produced in the testicular organ (gonad) of male human beings and animals. Like the female gamete (oocyte), sperm cells carry a total of 23 chromosomes that are a result of a process known as meiosis. In both animals and human beings, among many other organisms, these cells are involved in the sexual ... WebIn the study of evolutionary biology, homology refers to the existence of shared ancestry between a pair of structures or genes in a different classification unit or taxa. The term “homologous structures” refers specifically to similar structures found in different species that have a common ancestry or developmental origin.

WebProcessing of eukaryotic mRNA: Newly synthesized mRNA is called pre-mRNA. It is quite different from the mRNA that takes part in protein synthesis. At 5′ end of mRNA, a cap of 7-methylguanosine (m 7 G or 7 Me G) is added. At 3′-end a tail consisting of 80-200 adenine nucleotides called Poly (A) tail is added. WebThis artificial oligo-dC tail is then used as an annealing site for a synthetic oligo-dG primer, allowing synthesis of the second strand. (d) Homopolymer Tailing: This approach uses the enzyme terminal transferase, which can polymerize nucleotides onto the 3′-hydroxyl of both DNA and RNA molecules. We carry out the synthesis of the first ...
