Codons are three bases made up of (A, G, C, and/or U)
Deletions of one or more bases, insertions of one or more bases or Duplication, translocations and inversions of multiple bases
What are some examples of frameshift mutations?
During DNA replication, a DNA strang that has the bases ATTCGA produces a strand with the bases ...
