Which of the following is not a part of the nucleotide?(a) Phosphate g

1.	Which of the following is not a part of the nucleotide?(a) Phosphate group(b) Nitrogenous base(c) Pentose sugar(d) GuanosineThis question was addressed to me in a job interview.This interesting question is from Structure of a Polynucleotide Chain topic in portion Molecular Basis of Inheritance of Biology – Class 12
Answer» Correct CHOICE is (d) Guanosine To explain I would SAY: Guanosine is the STRUCTURAL component of RNA. Guanosine is a PURINE adenosine. It has some neuroprotective properties. The other three are the backbone of the nucleotide in the DNA.
