Chapter 3: Q23P. (page 78)

Some RNA molecules are covalently modified by methylation at the N鈦秔osition in adenosine residues. Draw the structure of the modified nucleoside.

Short Answer

Expert verified

The methylated structure of adenine is N鈦�-methyladenosine.

Step by step solution

01

Introduction

Nucleotides are the chemical building units of nucleic acids. It is a three component molecule that is made up of a nitrogenous base, a sugar ribose or deoxyribose, and at least one phosphate group. The nucleotide's nitrogenous bases are a purine or pyrimidine base connected to ribose in RNA.

02

Adenine is a purine base. it is a bicyclic, planer molecule that forms two hydrogen bonds with thymine. The structure of N-methyladenosine, a ribonucleic acid modification, is shown (mRNA) where the N鈦� location of the adenine base is methylated.
