In a nucleus, the number of RNA nucleoside triphosphates is 10 times more than the number of DNA nucleoside triphosphates, still only DNA nucleotides are added during the DNA replication, and not the RNA nucleotides. Why?

Text Solution

Verified by Experts

DNA polymerase is highly specific to recognise only deoxyribonucleoside triphosphates. Therefore. It cannot hold RNA nucleotides.
