Detailed explanation-1: -A special type of covalent bond called a phosphodiester bond forms between nucleotides. These phosphodiester bonds form the two strands that make up the DNA molecule.
Detailed explanation-2: -Answer and Explanation: Nucleotides within a single strand of DNA are connected by covalent bonds. This statement is true. Nucleotides are joined together through dehydration reactions, and formed a specific type of covalent bond called a phosphodiester bond.
Detailed explanation-3: -Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Detailed explanation-4: -Each base pair is formed from two complementary nucleotides (purine with pyrimidine) bound together by hydrogen bonds.
