Terms to Know
Base-Pair substitution

A type of gene mutation in which the wrong nucleotide is paired with a base during the process of DNA replication. The effects can range from none at all to life threatening.

DNA Polymerases

An enzyme that assists in the process of DNA replication.

DNA Replication

The process of replicating DNA before a cell divides.

Gene Mutation

A change in the sequence of nucleotides in a gene.

Semiconservative Replication

Half of a DNA molecule produced by DNA replication is "old" coming from the original strand of DNA and half is "new" and produced using the "old" strand as a template.
