Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of bond forms between the two strands of DNA?
A
Polar Covalent
B
Hydrogen
C
Ionic
D
Phosphodiester
Explanation: 

Detailed explanation-1: -Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing. These hydrogen bonds are individually weak but collectively quite strong. a template during DNA replication.

Detailed explanation-2: -The 2 strands of DNA are held together by hydrogen bonds between N2 bases.

Detailed explanation-3: -Each DNA molecule consists of two nucleotide chains wrapped around each other in a double helix and held together by hydrogen bonds. This hydrogen bonding involves only the nitrogenous bases. Each of the purine bases can hydrogen bond with one and only one of the pyrimidine bases.

Detailed explanation-4: -Covalent bonds are found in the DNA backbone (known as phosphodiester bonds).
