Splice site mutation. A splice site mutation is a genetic mutation that inserts, deletes or changes a number of nucleotides in the specific site at which splicing takes place during the processing of precursor messenger RNA into mature messenger RNA.
Lesson Summary. Stop codons are sequences of DNA and RNA that are needed to stop translation or the making of proteins by stringing amino acids together. There are three RNA stop codons: UAG, UAA, and UGA. In DNA, the uracil (U) is replaced by thymine (T). If a change in the DNA sequence, or mutation, of a gene occurs that creates a stop codon, this is called a nonsense mutation.
