Ovulation refers to the process of discharging of a mature egg from the ovary of a female. The discharging of the egg allows it to get fertilized by the sperm cells developed in a male. Generally, in humans, the only solitary egg is discharged at one time, however, on certain occasions, two or more get discharged at the time of the menstrual cycle.
The egg gets discharged from the ovary on the 14th to 16th day of about 28 days of the menstrual cycle. In case, if the egg does not get fertilized, the egg gets passed from the reproductive tract at the time of menstrual bleeding that begins about two weeks post ovulation.
Immature egg cell named as oocytes is released during ovulation. A female has limited number of eggs or immature oocytes and in a life span only 3000 to 500 egg matures and undergoes the process of ovulation. With the time and aging of women, this egg count reduces.
During ovulation a series of hormones such as Gonadotropin-releasing hormone, Follicle-Stimulating Hormone, Luteinizing Hormone, Progesterone and Estrogen are released to facilitate release of egg
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
