Detailed explanation-1: -Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time.
Detailed explanation-2: -Frameshift mutations The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of codons, or groups of three nucleotides.
Detailed explanation-3: -Meiotic mutations can be divided into four classes: (i) whole‐chromosome events caused by mis‐segregation during meiotic division, (ii) structural rearrangements caused by NAHR, (iii) mutations associated with gene conversion during recombination and (iv) point mutations.
Detailed explanation-4: -Missense Mutation A missense mutation is a DNA change that results in different amino acids being encoded at a particular position in the resulting protein. Some missense mutations alter the function of the resulting protein.
Detailed explanation-5: -(myoo-TAY-shun) Any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment. Mutations can be harmful, beneficial, or have no effect.
