Detailed explanation-1: -A point mutation is where you change one base in the DNA to another. A missense mutation occurs when that point mutation causes a different amino acid to be placed from that codon. Because multiple codons code for the same amino acid, not all point mutations will cause a missense mutation.
Detailed explanation-2: -One type of frameshift mutation is called insertion. As the name implies, an insertion occurs when a single nitrogen base is accidentally added in the middle of a sequence. This throws off the reading frame of the DNA and the wrong amino acid is translated.
Detailed explanation-3: -In the case of silent mutations, the substituted base pair still results in the overall codon it lies within to code for the same amino acid, due to the degeneracy of the genetic code.
