Detailed explanation-1: -Repeating units in DNA molecule is nucleotides. It contains phosphoric acid, nitrogenous base and deoxyribose sugar. Nitrogen base like Adenine, Guanine, Cytosine and Thymine are present.
Detailed explanation-2: -The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base-(cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
Detailed explanation-3: -The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue.
Detailed explanation-4: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
Detailed explanation-5: -So the repeating units of DNA strand are known as nucleotides.
