Nucleic acids can be found in two forms in the body: DNA (deoxyribose nucleic acids) and RNA (ribose nucleic acids)
All the DNA is contained in the nucleus of a eukaryote cell. The RNA can be found in three forms; mRNA, tRNA and rRNA.
Nucleotides are the monomers of DNA, they consist of three components:
- A phosphate group
- A 5-carbon (pentose) sugar
- A inorganic nitrogenous base
They are all joined together through covalent bonds. Nucleotides differ in two ways:
- They can either have a deoxyribose or ribose sugar
- They can have 5 different bases (Adenine, Thymine, Guanine, Uracil and Cytosine)
Nucleotides can be joined together through a condensation reaction between the sugar group of one nucleotide and the phosphate group of another nucleotide.
Formation of DNA:
DNA is called a polynucleotide. It is made up of two anti-parallel strands which are joined together with hydrogen bonds.
