Y-shaped region on a replicating DNA molecule where the parent strands are separated and replication of new strands can occur
adds new DNA nucleotides to a replicating DNA molecule
glues together fragments of DNA by joining breaks in the sugar-phosphate backbone
Sequence of RNA primers bound to a region of single-stranded DNA to initiate DNA replication.
model of DNA replication where the replicated molecules of DNA contain one strand from the original template molecule and one newly synthesized strand
