Definitions:

Nitrogen Bases

Organic molecules that serve as the building blocks of nucleotides, which in turn make up nucleic acids like DNA and RNA. The main nitrogen bases are adenine, thymine, cytosine, guanine, and uracil.

RNA Primer

The sequence of about five RNA nucleotides that are synthesized during DNA replication to provide a 3' end to which DNA polymerase adds nucleotides. The RNA primer is later degraded and replaced with DNA.

RNA Primase

An enzyme that creates a short RNA primer as the first step in DNA replication, necessary for DNA polymerase to initiate synthesis.

Okazaki Fragments

Short sequences of DNA nucleotides which are synthesized discontinuously and later joined together during DNA replication on the lagging strand.
