Question:

Why does the cell need RNA primer during DNA replication?

Hemalatha R.
Answer:

DNA Polymerase is the enzyme which brings about the extension of the daughter strand. However, this enzyme requires a free 3'-OH group for adding the nucleotides. Thus to provide for such free 3'-OH groups, RNA primers are added to the strand before the start of daughter strand synthesis.
