Explain DNA replication

1. DNA helicase unwinds the two strands 2. Primase adds RNA primers to mark where the copying of the base sequence will start 3. DNA polymerase va haciendo covalent bonds between nucleotides, adding them in the leading strand 5' to 3' direction. Luego it adds the nucleotides in the lagging strand poco a poco 4. exonuclease takes primers away 5. DNA polymerase fills gap again 6. ligase seals fragments between DNA to make two continuous strands
