By what 2 different mechanisms could mutant phages change to become capable of lysing e. coli k

The switching from lysogenic to the lytic cycle, also called lysogenic induction, can be caused by a double-stranded break in the prophage or can be caused by a mutagen. These factors could cause disruption of the cI & cro genes that are responsible for regulating the lytic-lysogenic cycles of bacteriophages..

"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."
