But not always: a silent mutation is a type of mutation in the coding region of a gene that doesn't actually change the amino acid sequence of the protein that is made. Below, learn how silent mutations work and why they're no big deal for an organism.
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA.The term frameshift mutation indicates the addition or deletion of a base pair. single point mutation can change the whole DNA sequence. Changing one purine or pyrimidine may change the amino acid that the nucleotides code for. Point mutations may arise from spontaneous mutations that occur during DNA replication. The rate of mutation may be increased by mutagens.
