What sorts of genetically engineered technologies are individuals allowed to copyright?

One is a synthetic gene or protein. This is the king that has no origin from organisms but has been chemically developed in a laboratory.  The other is the combination of genetic material from multiple organisms tantamount to the reconfiguration of naturally-occurring genetic elements that surpasses a particular set threshold of originality.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
