Question

A molecule of dna is a polymer composed of
A) Amines B) Nuceotides C) Chromosomes D) Fattyacids

Answer 1

Answer:

The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rule hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA. So, nuclotides are building blocks of DNA and not glucose or aminoacid. So option b is the correct answer.
