In the structure of DNA, where are the sugar-phosphate groups and the nitrogenous bases located?

Sugar-phosphate groups lie on the outside, and bases lie on the inside.

Sugar-phosphate groups lie on the inside, and bases lie on the outside.

Both sugar-phosphate groups and bases are on the outside.

Both sugar-phosphate groups and bases are on the inside.

Which best describes base pairing ?

A pyrimidine can only pair with a purine.

Purines and pyrimidines pair randomly with each other.

A pyrimidine can pair with either a purine or pyrimidine.

Only purines can form hydrogen bonds with each other.

Which of the following is the correct base pairing for DNA ?

A-T (2 H-bonds) C-G (3 H-bonds)

A-U (2 H-bonds) C-G (3 H-bonds)

A-T (3 H-bonds) C-G (2 H-bonds)

In nucleotide formation , what is phosphorylation ?

Removal of water to add a phosphate group to a sugar or existing phosphate group

Addition of a hydroxyl group to a sugar

Removal of a phosphate group from a molecule

What happens if AMP (adenosine 5'-monophosphate ) is phosphorylated ?

It becomes ADP (adenosine diphosphate) and then can be further phosphorylated to form ATP (adenosine triphosphate).

It breaks down into adenosine and phosphate ions.

It becomes cAMP (cyclic adenosine monophosphate) immediately.

It forms only ATP directly without any intermediate.
