[Year 1 Molecular Biology] 以下邊一個係substrate for primase?

Hi thank you so much for reading my question
I would like to ask which of the following is the substrate for primase? (其實咩係primase, 要有咩條件先可以做到substrate for primase?)
A. Guanine
B. Cytosine
C. Uracil with sugar
D. thymine  with sugar and 1 phosphate group
E. Adenine with sugar and 3 phosphate groups
麻煩哂

I guess D, thymine with sugar and 1 phosphate group. It looks like a typical 3'-end from which a primer unit is built.

Primase is an enzyme that synthesizes the primer for DNA replication.

利申: Not a major in molecular biology. Know very very little about this topic. :P

好似係喎,ATGC 有陣U(for RNA) 係basic amino acid to synthesize DNA,而一個DNA building block 係由是但1隻amino acid + heaxose + phosphate group 組成。如果primase 係DNA related enzyme的話,答案就應該係D
