A scientist is interested in producing flowers with a darker red color To do this, the scientist alters the promoter the gene make This transcription and increased rod pigments The scientist then alters the promoter to make it even more active This results in white flowers with no red pigment research showed an increase in siRNA in the cell What did the siRNA do to the mRNA

"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."
