A quantitative amino acid analysis reveals that protein X contains 0.58% tryptophan (Mr 204) by weight. (a) Calculate the minimum molecular weight of protein X (i. e., assuming there is only one tryptophan residue per protein molecule). (b) Gel filtration of protein x gives a molecular weight estimate of 70,000. How many tryptophan residues are present in a molecule of this protein

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

the answer to your question is:

c. complementary base-pairing
