Frameshift mutations most often happen when one or more nucleotides are inserted or deleted from the DNA. This can result in a completely new codon sequence that results in the production of non-functional proteins. It applies to the reading frame (sequence of codons) being changed. Which of the following choices are correct?
1) most often happen when one or more nucleotides are inserted or deleted from the DNA.
2) can result in a completely new codon sequence that results in the production of non-functional proteins.
3) applies to the reading frame (sequence of codons) being changed.
4) All of the choices are correct.
5) B and C only are correct.
