Identify the correct statement

Easy

A

Double helix model for DNA structure is based on the X-ray diffraction data produced by Watson and Crick
B

The linkage of nucleotides into a polynucleotide involves a dehydration reaction.
C

Prokaryotic cells lack nuclei and do not use mRNA to convey a message from the DNA to ribosomes.
D

Nitrogenous bases are a part of the backbone forming the nucleotide polymer.

Solution

The linkage of nucleotides into a polynucleotide involves a dehydration reaction. In the polynucleotide, adjacent nucleotides are joined by a phosphodiester linkage, which consists of a phosphate group that links the sugars of two nucleotides.
Double helix model for DNA structure is based on the X-ray diffraction data produced by Maurice Wilkin and Rosalind Franklin.
Prokaryotic cells lack nuclei but still use mRNA to convey a message from the DNA to ribosomes.
Sugar and phosphate form the backbone of the nucleotide polymer.
