Your colleague who is a medical geneticist seeks your help in interpreting a patient an XXY girl. Usually insertions and the subsequent frameshift mutation will cause the active translation of the gene to encounter a premature stop codon resulting in an end to translation and the production of a truncated protein. There are two kinds of substitution mutations one is a missense mutation. Because codons are read in groups of three nucleotides starting from the end of the last codon these mutations alter every subsequent codon.

Mutation in bacteria has some results such as missense nonsense silent frameshift lethal suppressor and conditional lethal mutation. Also it lets you know the difference between replication and when mutation occurs. There are two types of Frameshift Mutations and they are Insertion mutations A mutation where an extra base is inserted into a base sequence Deletion mutations The loss of a single base is deleted and the reading frame is shifted 9. Missense mutations This point mutation results in the replacement of one nucleotide by another. This mutation may have an adverse effect in Suppose there is a frame shift mutation in codon 2 a nucleotide is deleted ATG 111 223 334 445 556 Now every single codon after the frameshift in codon two is being misread and quite likely Frameshift mutations occur when the number of deleted or inserted base pairs is NOT a multiple of three. it will have no effect on protein function b. a missense mutation. frameshift mutation 14. point mutations in which one base is inserted into the DNA sequence.
