Where do you need ribonucleotides during DNA replication? HINT: They play TWO different roles
Ans. The requirement of RNA ribonucleotides during DNA replication are as follow-
#I. As RNA primer: DNA polymerase can’t synthesize new DNA strands on their own, they only extend a previously synthesised RNA primer by primase. The RNA primers are polymer of ribonucleotides.
#II. As energy molecule: ATP, the primary energy molecule for cellular processes, is also a ribonucleotide. ATP is required during unwinding of double stranded DNA helix by topoisomerases and DNA B helicase.
