DNA- Deoxyribonucleic Acid is a molecule composed of two chains or double strands that coil around each other forming a double helix to carry the genetic information for the development of an organism.
<u>Explanation:</u>
- DNA contains the information that instructs a living organism to develop, grow, survive and reproduce.
- The information instructed is found inside every cell and is passed down from parents to their children.
- DNA is made of nucleotide molecules which in turn contains a phosphate group, a sugar group, and a nitrogen base.
- Deoxyribose in DNA is another form modified from ribose sugar.
The answer is option C. Number of double covalent bonds between carbon atoms is responsible for causing different shapes of saturated and unsaturated fatty acids. The double covalent bond causes kink in the unsaturated fatty acids because of which their stacking is disrupted and they become loosely packed. The problem with double covalent bond is that unlike single covalent bond it can't rotate and has almost cis-configuration. This is also the reason behind their liquidity at room temperature.
