Nucleic acids are one of the four types of biological molecules in nature. The other three being: proteins, carbohydrates, lipids. Nucleic acids consists of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA).
DNA is a nucleic acid found in the NUCLEUS of eukaryotic cells or nucleoid region of prokaryotic cells where it functions to store or hold genetic information for the cell. On the other hand, RNA functions to carry the stored information in order to be expressed. Hence, according to this question, the nucleic acid functions to carry heredity information.
In the ovarian cycle, the surge of LH triggers ovulation.
During evolution when the level of estrogen is sufficiently high, it produces a sudden release of LH, usually around day thirteen of the cycle. This LH peak triggers a complex set of events within the follicles that result in the final maturation of the egg and follicular collapse with egg extrusion.
A surge in LH causes your ovary to release a mature egg around the second week of each menstrual cycle. A high LH level around this time means that you're at that moment in your cycle when you're most likely to get pregnant. Levels of LH are low for most of the monthly menstrual cycle. However, around the middle of the cycle, when the developing egg reaches a certain size, LH levels surge to become very high.
