DNA Mutation

This video is kind of self-explanatory, but it follows the replication of DNA and shows how an incorrect amino acid can be coded for. Once the double-stranded DNA strand is cut apart, the single strands are matched with complementary nucleotides. Sometimes this does not happen correctly, either the wrong nucleotide is matched or their is one nucleotide on the strand left uncoded. This affects which amino acid the sequence codes for, and sometimes one change codes for a different nucleotide. This is an example of how small fluctuations can have large repercussions on the nanoscale in Biology.
