In DNA replication, the leading strand _____________________.

is formed in a continuous sequence because DNA polymerase produces strands in a 5’ to 3’ direction

uses fragments connected by ligase to form a new strand of DNA because the DNA clamp cannot hold the DNA polymerase in place

is replicated in a discontinuous fashion because DNA polymerase produces strands in a 3’ to 5’ direction

does not require any DNA polymerase enzymes to form a new strand of DNA
