THE ROLE OF DNA AND RNA IN REPLICATION

Introduction
The standard view of molecular biology says that DNA keeps information about all our proteins and that they exist three types of RNA. Which, actively transform the codes to polypeptides. Of the three, the mRNA is responsible for transporting the information from the DNA to the ribosomes. The ribosome that converts the codes to amino acids.Deoxyribonucleic acid, or commonly referred to as DNA, is a molecule that is found inside every cell and which contains genetic information, (Hall 2011). The parent transmits the genetic information stored in the DNA to the offspring during reproduction. Two strands make up the DNA structure, which coil together to form a double helix. Each strand has four nucleotides within it. Which include cytosine; thymine, guanine and adenine, abbreviated as C, T, G and A respectively. Thymine and Cytosine are pyrimidines while guanine and adenine are purine bases.
This is what happens during DNA replication. An enzyme known as DNA gyrase initiates the splitting of the double helix, making them separate. Single strand binding proteins bind with each side for a while. After which the enzyme DNA polymerase passes through the strand creating or adding on new nucleotides. Then the nucleotides pair with other corresponding nucleotides. Finally, the enzyme DNA ligase joins the strand into one long strand.
