A Study on Molecular Biology, DNA and the Diverse Types of Proteins

            Molecular Biology is the study of cellular biology on a molecular level which is where DNA molecules are, which is what give people their heredity.  DNA, or Deoxyribonucleic acid, has two strands that is called the double helix. Each strand is a sugar phosphate back bone. (Simon, 2013, p. 174) Connecting these strands are four nitrogenous molecules known as Adenine, Thymine, Guanine, Cytosine. These molecules are known as nucleotides. Adenine always connects with Thymine and called a base pair. Likewise, Guanine always attaches with Cytosine, and they are a base pair.

This base-pairing acts like a code when DNA is ready to duplicate its self. When
