Make a frameshift mutation use brackets to indicate how the reading frame would be altered by the mutation
ATGCGTCCATGA

Original reading frame=> (ATG)(CGT)(CCA)(TGA)

Altered reading frame => (ATG)(CAC)(GTC)(CAT)(GAG)

Explanation: A frame shift mutation is a type of mutation in which there is addition or deletion of one or more nucleotides in a DNA sequence which results in alterations in the original reading frame of the DNA sequence. In the altered reading frame above two nucleotides were added at positions 4 and 5 thereby changing the subsequent reading frame of the DNA. Frame shift mutation can result in permanent change in DNA sequence during replication and subsequently in altered RNA sequence during transcription and altered amino acid sequence of the final gene product.

"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."

the correct answer is 2 and 4
