Can someone explain it for me in simple terms? I've tried searching the answer but it doesn't make sense to me.
It's for AQA Alevel biology.

In simple terms, due to the shapes of the structures involved (as you'll come across so often with enzymes), DNA polymerase can only add new nucleotides to the 3' end of the strand, so the strand expands in the direction moving from the 5' to the 3'.

Yes^^ Because remember enzymes are specific/complementary so can only bind to 3' end
