Functional Genomics

A number of methods are under development for treating genetic disorders, including a  inherited (eg, monogenic/Mendelian) conditions and acquired conditions such as cancer and infections. This topic reviews molecular techniques that can be used to alter the sequence or expression of a gene, including gene therapy, gene editing, and gene silencing.

Fertilization and Embryogensis is the process of Fusion of sperm and ovum to form ZygoteFertilization usually take place in oviduct. Ovum is in secondary oocyte stage during fertilizationSecondary oocyte is surrounded by two layer-zona pellucida and zona reticulateSperm move toward the secondary oocyte and bind to the receptor on zona pellucida. After sperm enter the oocyte, the zona pellucida become fertilization membrane preventing other sperm to enter. It is the entry of sperm that stimulate second meiotic division of Oocyte Acrosome of sperm release proteolytic enzyme (Hyaluronidase) that digest the egg wall and then the pro-nucleuses fuse form zygote (2n).

Zygote undergoes repeated cell division called cleavage. Cleavage starts as the zygote moves down from oviduct to uterus 3-5 days after fertilization, zygote develop into ball like structure of cell with central cavity; blastocyst (Blastula stage).Outer cell of blastocyst is known as trophoblastic cell while inner cell is known as embryonic cellTrophoblastic cell secrete HCG (human chorionic gonadotropin) hormone; similar in function as LHIt Prevent degredation  of corpus luteum, therefore corpus luteum continue to secrete progesterone and oestrogen, which help continuous growth of endometrium wall causing menstruation cycle to stop.
