Solution

DNA is formed by two polynucleotides that wrap around a central axis forming a right-handed double helix. The polynucleotides themselves are made up of deoxy-ribonucleotides in DNA and ribonucleotides in RNA.

The deoxyribonucleotides are made up of the sugar deoxyribose and the bases adenine, thymine, cytosine and guanine. The ribonucleotides are made up of the sugar ribose and the bases adenine, thymine, cytosine and guanine.

DNA is normally double stranded, but RNA is usually single stranded.

The two strands in DNA are antiparallel, which means one runs 5’-3’ while the other 3’-5’. The diameter of the DNA molecule is 20 angstroms, one turn is 34 angstroms, and one base pair 3.4 angstroms.

Note: Paragraph 2. Bold

1. Nucleotides consist of sugar, phosphate and base. Option “phosphate” is not mentioned in the list. It could have been better if the sentence could be written as “The deoxyribonucleotides are made up of the sugar deoxyribose, phosphate and the bases adenine, thymine, cytosine and guanine. The ribonucleotides are made up of the sugar ribose , phosphate and the bases adenine, thymine, cytosine and guanine.”

Or, The deoxyribonucleosides are made up of the sugar deoxyribose and the bases adenine, thymine, cytosine and guanine. The ribonucleosides are made up of the sugar ribose and the bases adenine, thymine, cytosine and guanine.

2. Nucleosides consists of base and sugar, but no phosphate. Option “nucleoside” is not mentioned in the list.

3. Polynucleotides are polymer of nucleotides. With respect to DNA or RNA each polynucleotide represents a strand.
