A<unk>  is an enzyme that assists in DNA replication. Such enzymes catalyze the<unk> ymerization of deoxyribonucleotides alongside a DNA strand, which they "read" and use as a template. The newly-polymerized molecule is complementary to the template strand and identical to the template's partner strand.<unk>  is considered to be a holoenzyme since it requires a magnesium ion as a co-factor to function properly. In the absence of the magnesium ion, it is referred to as an apoenzyme.<unk>  initiates DNA replication by binding to a piece of single-stranded DNA.
