BIOMOLECULES AND ENZYMES

Detailed explanation-1: -ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone ” of the RNA polymer and binds to nitrogenous bases.

Detailed explanation-2: -Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).

Detailed explanation-3: -D-ribose is a naturally occurring monosaccharide found in the cells and particularly in the mitochondria is essential in energy production.

Detailed explanation-4: -An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G).

Detailed explanation-5: -The naturally-occurring form, d-ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes. It has a structural analog, deoxyribose, which is a similarly essential component of DNA.
