Understand the types of mutations: A mutation is a change in the DNA sequence. The main types are nonsense, missense, silent, and frameshift mutations.
Nonsense mutation: This type of mutation introduces a premature stop codon in the DNA sequence, leading to a truncated and usually nonfunctional protein.
Missense mutation: This mutation results in a single amino acid change in the protein sequence, which can affect protein function depending on the importance of the altered amino acid.
Silent mutation: This mutation does not change the amino acid sequence of the protein due to the redundancy in the genetic code, typically having no effect on the protein function.
Frameshift mutation: This mutation involves the insertion or deletion of nucleotides that are not in multiples of three, altering the reading frame of the gene and potentially leading to a completely different and nonfunctional protein.
