The hormone which initiates the cycle events in a female ovary is the Follicle stimulating hormone (FSH).
The menstrual cycle is a complicated physiological process that happens in females of reproductive age. It normally lasts 28 days but can vary depending on the individual. The cycle begins with the release of follicle-stimulating hormone (FSH) from the pituitary gland at the base of the brain. FSH is essential for the growth and maturity of ovarian follicles, which are tiny sacs within the ovary containing immature eggs. FSH increases the formation of multiple follicles, but only one will fully mature and release an egg, a process known as ovulation. The menstrual cycle begins with the formation of the corpus luteum and the release of additional hormones such as luteinizing hormone (LH) and progesterone.

dna ligases are important enzymes that are essential for dna replication and repair in all organisms. based on the graphs shown here and your knowledge of human enzymes, at what temperature and ph is human dna ligase likely to have maximal efficiency?
The enzyme is just a thermostable DNA ligase since it exhibits its best nick-joining activity at 65–70 °C and maintains its DNA ligation ability even after being heated at 100 °C for two hours.
What causes the ligation reaction carried out in a cool environment?The ligation reaction was performed at a temperature that compromises between the ideal temperatures of bringing the DNA end together (1°C) or the enzymatic reaction (25°C), as the DNA ligase enzyme reaches its peak activity at this temperature.
Can a ligation be kept at room temperature?Ligations can be performed overnight and perhaps even for a couple of days if you're extremely busy at room temperature and even cooler (think 12-16°C). A ligation can also be kept in the refrigerator and taken out later for continue ligating as room temp for however long is required.

An O-glycosidic bond is shaped when the anomeric carbon of the sugar lays out a connection with the oxygen particle in the hydroxyl gathering of the liquor.
On the off chance that the anomeric carbon of the sugar makes the connection with the nitrogen particle of an amine, the bond is alluded to as an N-glycosidic bond.
Two monosaccharide units can be consolidated by glycosidic security — this is the essential linkage among the monosaccharide building blocks tracked down in all oligosaccharides. The glycosidic bond is framed between the anomeric carbon of one monosaccharide and a hydroxyl gathering of another.
The β-1,4-glycosidic bond has the hydroxyl bunch facing up. 1,4-glycosidic bonds can be tracked down in both amylase and amylopectin in starch. These linkages make stretching in the polysaccharide.

how does an abundance of tryptophan inhibit the production of more tryptophan?
Tryptophan suppresses self-production as it builds up by activating a repressor protein, that binds towards the operator and prevents transcription. Tryptophan synthesis enzymes are not produced.
This repressor-tryptophan receptor complex to the trp operator when tryptophan is abundant. Because RNA polymerase cannot bind to this binding, the codon is not transcribed. On the other hand, the operon is translated when tryptophan levels drop because the repressor is unable to bind the operator. It is wasteful to produce the tryptophan-synthesizing enzymes if tryptophan levels are elevated as well as its synthesis is not required because doing so is metabolically expensive. When tryptophan rates are elevated, a corepressor binds the repression protein to a operator sequence, suppressing the trp operon.
