The initial nucleotide chain that is produced during DNA synthesis is a short stretch of RNA. Starts a complimentary RNA chain so that DNA synthesis can continue.
Bind to the unpaired DNA strands after parental strands separate, keeping them from reconnecting
Produced by mitotic division of a zygote, multicellular diploid.
