Nucleic acids

Explanation:

Remember these long strands could be the ADN or the RNA, in both cases, they are formed by nucleotids, that means a complex of three parts.

A nucleotid is conformed by:

a) a nitrogenous base that in the case of DNA could be Adenine (A), Guanine (G) , citocine (C) o thymine (T). In the case of ARN are almost the same, the difference is instead of having Thymine, it will have uracile (U).

b) a phosphate group

c) a carbohydrate, in the case of ADN it will be Dexosyrribose and in the case of ARN will be ribose sugar.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
