Chapter 27.6, Problem 10P

Interpretation Introduction

Interpretation:

The way in which the structures of trinucleotides AUG and GUA having all of the pentoses as $\text{d-ribose}$ differ from the given trinucleotide is to be explained.

Concept Introduction:

Trinucleotide is a nucleotide consisting of three mononucleotides in combination.

Two nucleotides are joined by a phosphodiester unit.

A phosphodiester unit connects the $3\text{'}\text{-oxygen}$ of one nucleoside to the $5\text{'}\text{-oxygen}$ of the other nucleoside.

Nucleotide sequence is read in such a way that it starts at the free $5\text{'}\left({\text{CH}}_2\text{OH group}\right)$ end and proceeds towards the free $3\text{'}\left(\text{OH group}\right)$ at the other end.
