WebOct 4, 2024 · In general, a mutation is when a gene is altered through a change in DNA structure; this may refer even to entire sections of chromosomes. A point mutation is specifically when only one nucleotide base is changed in some way, although multiple point mutations can occur in one strand of DNA or RNA. From DNA to Protein WebNov 4, 2024 · A deletion changes the DNA sequence by removing at least one nucleotide in a gene. Small deletions remove one or a few nucleotides within a gene, while larger deletions can remove an entire gene or several neighboring genes. The deleted DNA may alter the function of the affected protein or proteins. Deletion-Insertion

WebThe first step in decoding genetic messages is transcription, during which a nucleotide sequence is copied from DNA to RNA. The next step is to join amino acids together to form a protein. The order in which amino acids are joined together determine the shape, properties, and function of a protein. WebHere is a quick summary of a few of these: Substitution A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G).
