Uracil vs. Thymine

RNA uses Uracil in place of Thymine.

2
New cards

N-Glycosidic Linkage

A nitrogenous base is linked to the OH of the 1'C of pentose sugar via an N-glycosidic linkage.

3
New cards

Examples of Nucleosides

Examples include adenosine, deoxyadenosine, guanosine, deoxyguanosine, cytidine, deoxycytidine, uridine, and deoxythymidine.

4
New cards

Nucleotide Formation

Formed when a phosphate group is linked to the OH of the 5'C of a nucleoside through a phosphoester linkage.

5
New cards

3'-5' Phosphodiester Linkage

Two nucleotides are linked through this linkage.

6
New cards

Polynucleotide Chain Ends

It has a free 5' phosphate at one end and a free 3' hydroxyl group at the other end.

7
New cards

Nitrogenous base present in both DNA and RNA

Cytosine.
