Ribonucleic acid (RNA)

The backbone of RNA is composed of ribose rather than 2ˈ-deoxyribose. That is, it has a hydroxyl group at its 2ˈ position. RNA has uracil in place of thymine. Uracil lacks the 5ˈ methyl group which is present in thymine. RNA is a single polynucleotide chain. RNA functions as an intermediate (the mRNA) between the [...]

Ribosomes

The ribosome is a cellular machine found in all organisms. It serves to convert the instructions found in messenger RNA (mRNA, which itself is made from instructions in DNA) into the chains of amino acids that make up proteins. It is a sphere-shaped structure within the cytoplasm of a cell that is composed of [...]
