how do mutations give you cancer. some mutations of DNA in body cells affect genes that control cell division. describe how point mutations and frameshift mutations affect the synthesis of proteins. Point mutations change only one nucleotide in a codon, therefore only changing one amino acid in a protein. Point mutation does not affect the synthesis of proteins.
Frameshift mutation (illustration). This type of mutation occurs when the addition or loss of DNA bases changes a geneâs reading frame. A reading frame consists of groups of 3 bases that each code for one amino acid.A frameshift mutation shifts the grouping of these bases and changes the code for amino acids. nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.
