Structure Of DNA Questions and Answers (Q&A)

Cytosine and guanine

3 Answers

The correct answer to this question is 36%. In a situation like this with a double-stranded DNA, we know G (guanine) is always complementary with C (cytosine) and A (adenine) is always complementary with T (thymine).

Therefore, the percentage of G has to equal the percentage of C, and the percentage of A has to equal the percentage of T. If G=14% then C=14%, totalling 28%. Therefore A+T = 72% (the remaining out of 100%), and we know A has to equal T so we can divide 72% in half to obtain the equal parts A (36%) and T (36%).

The correct answer to this question is False. A bond is used to glue the Okazaki fragments together, but it isn't the glycosly bond. Instead, the glycosly bond is used to join ring shaped, sugar molecules to another group. This group may be a sugar or it could be something else. Hemiacetal groups of saccharides and the hydroxl group are how glycosidic bonds are formed.

Glycoside bonds may also be bonds between hemiacetal groups of sugars and groups other than hydroxlys. These groups can be glycosides, thioglycosides, or selenogylcosides. These bonds are covalent and an example of a glycosidic bond occurs in maltose.
