Every nucleotide ius made up of three components:
1) A pentose sugar (a sugar with five crabon atoms)
2)A phosphate group
3)A nitrogenous base (adenine, thymine, cytosine, guanine and urasil)
There is a specific process used to describe and explain how the three components are joined together which is called a CONDENSATION REACTION.
1. A condenstaion reaction (a loss of water) would join together the pentose sugar, phosphate group and nitrogenous base.
2. To form two mononucleotides (dinucleotide), the pentose sugar of one nucleotide would join with the phosphate group of the second nucleotide via a CONDENSATION REACTION.
3.The bond produced between them is called a PHOSPHODEISTER BOND.
4. Mononucleotides can keep linking to other nucleotides to form a POLYNUCLEOTIDE - a long chain of mononucleotides.
