Mutation webquest 2016.docx, 13.96 kb; Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning. Genomes, chromosomes, and dna web quest. Change a codon to one that encodes the same amino acid and causes no change in the protein produced. Because dna is the repository of genetic information in each living cell, its integrity and stability are essential to life. These alterations can be caused by random deletion is one last type of frameshift mutation and occurs when a nitrogen base is taken out of the sequence. Without mutation, evolution could not occur. Damaged dna can be mutated either by substitution, deletion or insertion of base pairs.
