Todescribe: The stages of the menstrual cycle in which the levels of the follicle-stimulating hormone arehigher than those of luteinizing hormone.
Introduction: The menstrual cycle consists of a monthly series of variations that occur in the female body for the preparation of pregnancy. The menstrual cycle includes four steps that are ovulatory, luteal, menstrual, and follicular. Hormones such as follicle-stimulating hormone and luteinizing hormone play a vital role in the menstrual cycle.

Explanation of Solution
Menstruation is the monthly bleeding in women. During the end of the menstrual cycle, the level of follicle-stimulating hormone exceeds the level of luteinizing hormone. The menstrual cycle starts with bleeding and considers as day 1, and the cycle ends just before the beginning of the next menstrual cycle.
The menstrual cycle is of around 28 to 36 days. The menstrual cycle is controlled by hormones that are produced by pituitary glands such as luteinizing hormone and follicle-stimulating hormone. These hormones further stimulate the production of progesterone and estrogen. Approximately around 27-28 and 1-2 in 28 days cycle, the level of follicle-stimulating hormone ishigher than the luteinizing hormone.

- You have identified a new species of a Gram-positive bacteria. You would like to screen their genome for all proteins that are covalently linked to the cell wall. You have annotated the genome, so that you identified all the promoters, operons, and genes sequences within the operons. Using these features, what would you screen for to identify a set of candidates for proteins covalently linked to the bacterial cell wall.arrow_forwardBelow is a diagram from a genomic locus of a bacterial genome. Each arrow represents a coding region, and the arrowheads indicate its orientation in the genome. The numbers are randomly assigned. Draw the following features on the diagram, and explain your rationale for each feature: 10 12 合會會會會長 6 a) Expected transcriptions, based on known properties of bacterial genes and operons. How many proteins are encoded in each of the transcripts? b) Location of promoters (include rationale) c) Location of transcriptional terminators (include rationale) d) Locations of Shine-Dalgarno sequences (include rationale)arrow_forwardSample excuse letter in school class for the reasons of headaches and dysmenorrhea caused by menstrual cyclearrow_forward
