DNA
What is DNA?
DNA is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses.
The structure of DNA.
The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structure of two base pairs are shown in the bottom right.
What DNA is made of.
DNA is made of adenine, thymine, cytosine and guanine.
DNA replication
DNA is located in the cells of living things. DNA replicates itself an carries hereditary information for living things. RNA strands are translated to specify the sequence of amino acids within proteins. These RNA strands are initially created using DNA strands as a template in a process called transcription.
RNA
Ribonucleic acid (RNA) is a polymeric molecule. It is implicated in a varied sort of biological roles in coding, decoding, regulation, and expression of genes.The three types of RNA are:
mRNA (messenger RNA) - carries genetic information from the nucleus to the cytoplasm
tRNA (transfer RNA) - brings amino acids to ribosomes during protein synthesis
rRNA (ribosomal RNA) - guides the translation of mRNA into a protein.
