In a DNA strand, the nucleotides are linked together by-----------.
In a DNA strand, the nucleotides are linked together by-----------.
Options
- AGlycosidic bond
- BPhosphodiester bond
- CPeptide bond
- DHydrogen bond
Correct answer
B. Phosphodiester bond
Step-by-step solution
In a DNA strand, adjacent nucleotides are joined together by phosphodiester bonds.
This bond is formed between the carbon atom of the pentose sugar of one nucleotide and the carbon atom of the pentose sugar of the adjacent nucleotide through a phosphate group.
Glycosidic bonds link a nitrogenous base to a pentose sugar.
Peptide bonds link amino acids in a polypeptide chain.
Hydrogen bonds link the complementary nitrogenous bases of two opposite DNA strands.
