Ribose sugar is not a component of
(a)AMP
(b)ATP
(c)DNA
(d)RNA
Solution
Hint Ribose sugar is a type of simple sugar that occurs naturally in the form of ribonucleotides as their components, which form from the RNA. It is not present in the genetic component of human beings.
Complete answer:
Ribose sugar is not a component of DNA. RNA constitutes ribose sugar which is a carbon sugar and is a monosaccharide. DNA consists of deoxyribose sugar which is linked to a nitrogenous base at the first carbon through a glycosidic bond. It is a pentose sugar. The DNA molecule is composed of two polynucleotide chains that coil around each other that forms a double helix that carries genetic instructions for the functioning, development, growth, and reproduction of all organisms and viruses. Each nucleotide consists of four nitrogen-containing nucleobases which include cytosine, guanine, adenine, and thymine which are a sugar and a phosphate group. These nucleotides are joined together by covalent bonds which are known as phosphodiester linkage and result In alternating sugar-phosphate backbone. The nitrogenous bases are bound together with hydrogen bonds to make double-stranded DNA and the complementary nitrogenous bases are divided into two groups which are pyrimidines and purines.
Additional information:
AMP: AMP is adenosine monophosphate which is a nucleotide that consists of a phosphate group and ribose sugar with adenine nucleobase which is an ester of phosphoric acid and nucleoside adenosine.
ATP: ATP is adenosine triphosphate which is an organic compound and provides many processes in living cells with energy and are found in all known forms of life and is known as the molecular unit of currency of intracellular energy transfer. It is consumed in metabolic processes and converts into adenosine diphosphate to monophosphate. The ATP gets regenerated by other processes so that the human body recycles its body weight which is equivalent to each ATP a day.
RNA: RNA is ribonucleic acid which is a polymeric molecule that helps in coding, regulation, decoding, and expression of genes. It is essential for all known forms of life and is an assembled chain of nucleotides that is found in nature as a single-strand folded onto itself.
So, the correct answer is 'DNA'.
Note: Ribose occurs naturally and is the rate-limiting compound in the production of energy, which acts as a fuel for our cells. It supplements with drivers which help in reaching fitness goals by using stones of ATP and replenish its energy compounds.
