DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). <span>DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.</span>

Sever21 [200]
<h2>Average life span population</h2>

Explanation:

  • A study done by the group of investigators in america determined that by decreasing the concentration of dnp will increase the average life from 719 days of a control population to 770 for dnp controlled population or by 1.07.
  • So the average lifespan of every individual will increases roughly 5.6 years so as average lifespan will increase from 719 to 770 days.
  • Hence, the right answer is " 5.6 years would be added the same percentage increase were observed."
