  • DNA Replication

    The process of replicating DNA before a cell divides.

  • DNA Polymerases

    An enzyme that assists in the process of DNA replication.

  • 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.

  • Gene Mutation

    A change in the sequence of nucleotides in a gene.

  • 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.
