BIOMOLECULES AND ENZYMES

Detailed explanation-1: -DNA stands for deoxyribonucleic acid and is double stranded and RNA stands for ribonucleic acid and is a single strand. RNA and DNA are similar chemically except the nature of sugar. Complete answer: DNA and RNA are nucleic acids and polymers of corresponding sugars and nucleotides.

Detailed explanation-2: -DNA uses thymine and deoxyribose sugar, while RNA uses uracil and ribose sugar. While DNA is usually molded into a double-stranded helix, RNA is usually single-stranded, which allows for the binding of anticodons during translation.

Detailed explanation-3: -Although DNA is often found as a single-stranded polynucleotide, it assumes its most stable form when double stranded.

Detailed explanation-4: -Unlike DNA, however, RNA is most often single-stranded. 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).
