DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand.
C) DNA polymerase adds nucleotides in the 5' to 3' direction. D) the strand made continuously is the leading strand. The strand made in pieces is the lagging strand. (And this is the reason DNA replication is considered semi-conservative)
