Deletions remove nucleotides, and insertions add nucleotides. Consider the following sequence of bases in RNA: AUG-AAU-ACG-GCU = methionine-asparagine-threonine-alanine

WebThis occurs for several reasons: a limited amount of CFTR protein is produced; only a small number of protein at the cell surface works correctly; or normal protein at the cell surface degrades too quickly, leaving small numbers of protein behind. WebNucleotide substitutions may lead to no change in the protein sequence (known as silent mutations ), change the amino acid sequence (known as missense mutations ), or create a stop codon (known as a nonsense mutation ). Insertions and deletions in protein coding sequences lead to frameshift mutations.
