Distinguishing features of several birth control methods designed to prevent ovulation from those that prevent fertilization. Introduction: Ovulation is the process of release of mature eggs from the follicles of ovaries. It is guided by the pituitary by Follicle Stimulating Hormone (FSH) produced by the pituitary which stimulates production estrogen. The luteinizing hormone (LH) from the pituitary triggers ovulation and stimulates the production of progesterone. The estrogen and progesterone together prepare the uterus to accept a fertilized egg. Fertilization is the process of zygote formation by the fusion of female gametes from the egg and male gametes from the sperm. By prevention of either ovulation or fertilization, birth control may be achieved successfully.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase

Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
