Question

Which of the following properties of DNA polymerase necessitates the synthesis of Okazaki fragments for the lagging strand

A. Requirement for primers

B. Exonuclease activity

C. Ability to copy DNA template only in 3’ to 5’ direction

D. Requirement for helicase to separate the DNA chains

8.During transamination amino groups of most amino acids are transferred to α-ketoglutarate to form which amino acid?

A.Leucine

B.Glutamate

C.Alanine

D.Aspartate

Answer 1

Solution

(1).(C).ability to copy DNA template only in 3’ to 5’ direction

Explainationd

duringthis DNA polymerase moves along the template strand in a 3'–5' direction, and the daughter strand is formed in a 5'–3' direction.

during this process DNA polymerase help to building of strand to direction so that produce the identical copies if this process not takes place then some damage occur

(2). (B). Glutamate

During transamination amino groups of most amino acids are transferred to α-ketoglutarate to from glutamate amino acid.

Glutamate is a main donor of amino group.

Total 17 types of amino acids form like this process.

And in this process transaminases enzyme require.
