Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which bond is present in the sugar and phosphate group in a nucleotide?
A
Phosphodiester bond
B
Peptide Bond
C
Ester Bond
D
Glycosidic Bond
Explanation: 

Detailed explanation-1: -The bond between the phosphate and hydroxyl group of sugar is an ester bond. DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds. Between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide.

Detailed explanation-2: -Explanation: The type of bond that holds the phosphate group to the sugar in DNA’s backbone is called a phosphodiester bond. Hydrogen bonds connect bases to one another and glycosidic bonds occur between deoxyribose groups and the base groups.

Detailed explanation-3: -These bonds are called phosphodiester bonds, and the sugar-phosphate backbone is described as extending, or growing, in the 5’ to 3’ direction when the molecule is synthesized.

Detailed explanation-4: -A phosphodiester bond is a group of strong covalent bonds between a phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds. They are found in DNA, RNA, etc.
