Osteoclasts absorb calcium from the bones and add this calcium into the blood to increase the calcium level. If calcium is present in very high amount so this calcium is stored in the bones of the body and extracted when needed by the body.
Answer:
The correct answer is DNA ligase.
Explanation:
DNA Ligase is an enzyme with links 2 strands of DNA by creating a bond between the phosphate group of 1 strand and deoxyribose group of the other strand of DNA.
In cells, it is used to join the Okazaki fragments together which are formed on the lagging strand during the process of DNA replication.
Okazaki fragments are tiny pieces of DNA nucleotide which are formed in a discontinued manner but latter they are joined by DNA ligase enzyme.
