Detailed explanation-1: -A nucleotide is a subunit of DNA or RNA that consists of a nitrogenous base (A, G, T, or C in DNA; A, G, U, or C in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA, and ribose in RNA). Adenine (A) is one member of the A-T (adenine-thymine) base pair in DNA.
Detailed explanation-2: -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-3: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
Detailed explanation-4: -A DNA molecule in a human chromosome can be up to 250 million nucleotide-pairs long; in contrast, most RNAs are no more than a few thousand nucleotides long, and many are considerably shorter.
Detailed explanation-5: -DNA is made of smaller subunits called nucleotides. Each nucleotide consists of three components: a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.
