DNA is composed of repeating units of ___________

DNA is composed of repeating units of ___________ Correct Answer deoxyribonucleotides

It is a long, double” chain of deoxyribonucleotide, or deoxyribotide, units. The two deoxyribonucleotide chains are twisted around a common axis to form a right-handed double helix (spiral) that encloses a cylindrical space in it. Each deoxyribonucleotide unit, in turn, consists of three different molecules: phosphate molecule, a 5-carbon deoxyribose sugar and a nitrogenous base.
