Question

What do gene mutations change?

  1. DNA
  2. RNA
  3. Proteins 
  4. Lipids 

Hint:

DNA is the genetic material of eukaryotic organisms.

The correct answer is: DNA


    DNA or deoxyribonucleic acid is the genetic material for all eukaryotic organisms. Mutation basically alters the genetic sequence attributing to the change in the normal DNA of the organism. The mutation in the nucleic acid sequence is the main reason of evolutionary changes in the world. Sometimes, these changes can be harmful as well.
    RNA or ribonucleic acid is the genetic material of few viruses. Even viruses undergo mutation, which is basically due to the lack of "proof reading activity" during multiplication of the RNA.

    • DNA or deoxyribonucleic acid is the genetic material of all eukaryotic organisms and few prokaryotic organisms
    • Mutation refers to change in the sequence of genetic material of an organism
    • RNA or ribonucleic acid is genetic material of few viruses alone
    • Lipids and proteins provide energy and form building blocks of life, respectively. They do not have any role in genetic mutation.
