BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Ribonucleic acid (RNA), unlike DNA, is usually single-stranded. A nucleotide in an RNA chain will contain ribose (the five-carbon sugar), one of the four nitrogenous bases (A, U, G, or C), and a phosphate group.

Detailed explanation-2: -Answer and Explanation: The single-stranded nucleic acid that contains the sugar ribose is RNA. RNA stands for ribonucleic acid and contains the four nitrogenous bases adenine, cytosine, guanine, and uracil. RNA is necessary in the actual construction of proteins via protein synthesis.

Detailed explanation-3: -A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

Detailed explanation-4: -Single-stranded DNA is a DNA molecule that consists of only a single strand contrary to the typical two strands of nucleotides in helical form. In nature, a single-stranded DNA genome can be found in Parvoviridae (class II viruses).

Detailed explanation-5: -Definition. Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.
