During proofreading, which of the following enzymes reads the DNA? primase topoisomerase DNA pol helicase
Please put these steps in the correct order.Is this for leading or lagging strand dsDNA pried apart. Nucleotides added on to the 3’ end of DNA. Single stranded DNA binding proteins bind. Initiator proteins bind dsDNA. RNA nucleotides are replaced with DNA nucleotides (proofreading while they go) RNA primer degraded. Primase begins replication.
