DNA Mutation is caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Thus, the correct answer is option D.
1.DNA Mutations are caused by environmental factors known as mutagens.
2.Types of DNA mutagens include radiation, chemicals, and infectious agents.
3.DNA Mutations may be spontaneous in nature.
A mutation in human ATPase 6 from leucine to
arginine at position 156 may allow the movements of protons across the
membrane, but not rotating of the ring of c subunits.
This possible mechanism affect the function of
ATP synthase because there would be an uncoupling of proton translocation and ATP
synthesis. ATP synthase would remain sensitive to F0 proton conduction
inhibitors
An abiotic factor is a non living thing
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. So, if these amino acids are in anyway related to each other, there can be some similar resemblance between the beetles.
