Answer:
The correct answer is Each nucleotide is connected to three nitrogenous bases.
- Deoxyribonucleic acid (DNA) is a genetic material composed of nucleotides.
- Each nucleotide is made up of three elements: a phosphate group, a sugar group (deoxy ribose), and a nitrogenous base.
- There are four types of nitrogenous bases found in the DNA : adenine (A), guanine (G), thymine (T), and cytosine (C).
- Phosphate binds to a sugar group with the help of ester bond and sugar binds to a nitrogenous base with the help of glycosidic bond.
- Nucleotides bind with each other with the help of phospodiester bond to form the polynucleotide chain.
- The two nucleotide chains are held together with the help of hydrogen bonding between nitrogenous bases of two strands. They form the double helical structure of the DNA.
- The two strands lei in anti-parallel orientation.
- It is also important to note that adenine always binds with thymine with the help of two hydrogen bonds and guanine always binds with cytosine with the help of three hydrogen bonds.
