Question

For DNA replication, primases: A) Create short pieces of DNA to provide 3'ends for DNA polymerases Unwind the DNA so polymerases can bind react more with the lagging strand than with the leading strand connect the okazaki fragments E) only work on the lagging strand is a wonderful thing, which michal is it not needed for? 20 Mg at the follow B) Functioning of splicing out of introns DNA polymerases Functioning of Acetyl carboxylase Functioning of Rubisco E) It's needed for all of these

Answer 1

19. Option A.

Primase is an RNA polymerase that are involved in the process of DNA replication that make short stretches of RNA sequences called primer.

20. E.

Reports are there providing the information regarding the necessity of Mg2+ for the splicing of group l introns.

DNA polymerase need Mg2+ for primer extension and for its 3' to 5' exonuclease activity.

Fatty acid biosynthesis by acetyl CoA carboxylase need the divalent cation Mg2+.

Mg2+ is necessary for the process of activation of the enzyme Rubisco. Low concentration of Mg2+ accelerate the activity of Rubisco and high concentration slows down the enzyme activity.
