Question

Through which among the following linkages are the two nucleotides connected through the 3’-5’ end?

• A. Phosphodiether linkage
• B. Phosphodisulphide linkage
• C. Phosphodinitrate linkage
• D. Phosphodiester linkage

Answer 1

Answer:

D. Phosphodiester linkage

When two nucleotides come close to each other, they form a linkage. This linkage is seen from the 3’-5’ end. This type of a linkage is called as the phosphodiester linkage. A phosphodiester linkage between 2 nucleotides forms a dinucleotide.
