The molecule responsible for the transformation of characteristics form one generation to the next is called DNA. The genetic material, located in the chromosomes is a combination of acid and histones. DNA is made up of units called nucleotides. Nucleotides are made up of 3 components, a five carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base. This base can be either adenine, guanine, thymine or cytosine. There are 2 strands of nucleotides in a double-helix …showed first 75 words of 601 total…

DNA carries traits from parents to child, and then to the child's children. As long as there are humans in the world, a person can never truly die because they traits will always be present in their offspring. BIBLIOGRAPHY 1.
