Which part of a dna molecule carries the genetic instructions that are unique for each individual: the sugar-phosphate backbone or the nitrogen-containing bases?

the nitrogen-containing bases

Explanation:

The nitrogen-containing base sequence of DNA contains all the genetic information which are encoded as mRNA during transcription and then translated into polypeptides during the process of translation/protein synthesis.

The genetic code (codon) is a sequence of 3 bases which codes for specific amino acids.

The sugar phosphate backbone of the DNA holds the DNA structure together and has a negative charge that makes the DNA to be water-soluble.

"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."
