Harmful mutations dna

WebMutation is a permanent alteration in the nucleotide sequence of DNA (deoxyribonucleic acid). As a result of mutation, the amino acid sequence of proteins encoded by the stretch of DNA or gene is changed, which in turn, may alter the composition and/or function of body cells and tissues. WebNeutral mutations can be silent - which means there is no difference in the amino acid sequence although an alteration has occurred in the genetic code. Silent mutations are due to the degeneracy or redundancy of the genetic code. Neutral mutations are often missense mutations, but can rarely be nonsense or frameshift mutations as well.
