does DNA polymerase only move in the 5' to 3' direction, and does anything happen in the 3' to 5' direction?

i tend to over analyze things in biology and tend to confuse myself

    Yes it moves in the 5' 3' direction

    DNA is anti-parallel. This means that one strand runs 5' 3', and the other strand runs 3' 5'.

    During DNA replication, the dna polymerase can copy nucleotides in a constant stream on the 5' 3' direction strand.

    In the 3' 5' strand, the placing of nucleotides occurs in chunks (called okazaki fragments), because it runs the opposite direction of the dna polymerase.

    It's kind of confusing but this video really helps

    As the strand unwinds in the 5' to 3' direction (on the leading strand), DNA polymerase replaces the RNA intermediate with the appropriate base. Since DNA polymerase will only move in the 5' -> 3' direction, on the lagging strand it creates Okazaki fragments, which are sealed together by ligase.

    DNA polymerase indeed replicates in the 5 to 3 direction,

    but some DNA polymerases have proofreading ability, which goes 3 to 5 , to check for any errors and correct incorrect sequences.

    The Manfreds. The song was even called 5-4-3-2-1, which I think was very nice of them.
