Proteins 1A and 1B are encoded from the same gene. Protein 1A is made up of five different protein domains in the following order: an N-terminal domain, a beta-sheet, a transmembrane domain, a globular domain, and a C-terminal domain.
Protein 1B consists of five domains in the following order: an N-terminal domain, a transmembrane domain, a globular domain, a second transmembrane domain, and a C-terminal domain.
Which is the most likely explanation for this?
protein processing
alternative splicing
frameshift mutation
alternative promoter usage
microRNA regulation

going to simply be the fifth answer bro

Explanation:

idk how to explain that lol biology is just memorized

"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."
