Regarding the structure of a polynucleotide chain (DNA or RNA), which of the following statements are accurate?
a. A nucleotide has three components: a nitrogenous base, a pentose sugar, and a phosphate group.
b. The pentose sugar in RNA is ribose, and in DNA is deoxyribose.
c. Cytosine is common to both DNA and RNA; Uracil is present in DNA at the place of Thymine.
d. A nucleoside is formed when a nitrogenous base links to the OH of the 1’C of the pentose sugar via an N-glycosidic linkage.
e. Two nucleotides are linked through 5′-3′ phosphodiester linkage to form a dinucleotide.
