Answer:
Each strand has a 3' end (unbound hydroxyl group) and a 5' end (hydroxyl group of deoxyribose sugar), the two strands run antiparallel to each other. (Ans. E)
Explanation:
DNA is known as Deoxyribonucleic acid. It is a complex organic molecular structure and present in all eukaryotes, prokaryotes and some viruses. For the transmission of inherited traits DNA codes genetic information.
It is a double-helix polymer consist of two spiral DNA strands fold around each other. Each strand of DNA is made up of a long chain of nucleotides. DNA's nucleotide consist phosphate group attached with deoxyribose sugar and nitrogenous bases two purine (adenine, guanine) and two pyrimidine (cytosine, thymine)
DNA have two distinct ends, one is 5'prime another is 3'prime. It means 5' and 3' carbon present on the sugar. 5' prime end consist phosphate group and 3' prime end consist hydroxyl group.
