You are investigating a mutant eukaryotic cell line that makes all of its mRNAs much longer than the mRNAs from normal cells. Intrigued, you examine the proteins in these cells and note that many of them are either much longer or much shorter than the normal proteins from nonmutant cells. Assuming there is just one mutant defect in these cells, which of the possibilities is most likely?a. A stop codon is mutatedb. The enzyme that adds the poly-A tail is defective. c. RNA polymerase does not recognize the terminator sequence. d. The spliceosome is nonfunctional. e. The release factor is defective.

"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."
