Detailed explanation-1: -The given statement that DNA is single-stranded and RNA is double-stranded is False. The DNA molecules which are present in the system are mainly double-stranded structures which are abundant in the body systems. The RNA molecule which is produced from the DNA with the help of transcription is single-stranded.
Detailed explanation-2: -DNA is generally double-stranded and RNA is generally single-stranded (though both can exist in either form). Prokaryotes contain both DNA and RNA.
Detailed explanation-3: -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).
