Explanation:
A ribonucleotide is very similar to a deoxyribonucleotide with the major difference being that they have a H instead of an OH in the 1’ carbon. Each ribonucleotide also has a phosphate molecule in their 5’ carbon like DNA. It is this phosphate that bonds with the 1’ carbon of the next monomer to form a phosphodiester bond through a condensation process – that releases a water molecule.
Carbon cycle is associated with fossil fuels
