Chapter 30, Problem 5P
Interpretation Introduction
Interpretation:
The property of heparin due to which it binds effectively to RNA polymerase and inhibits the transcription should be determined.
Concept introduction:
RNA synthesis (transcription) is the synthesis of an RNA molecule from the nucleotide’s adenine, cytosine, guanine, or uracil. The

Leaderless. The MRNA for the A repressor begins with 5'-AUG-3',
5'-AUG-3', which encodes the methionine residue that begins the
protein. What is unusual about this beginning? Would it cause the
MRNA to translate efficiently or not?
Complements. The sequence of part of an mRNA is
5'-AUGGGGAACAGCAAGAGUGGGGCCCUGUCCAAGGAG-3'
5'-AUGGGGAACAGCAAGAGUGGGGCCCUGUCCAAGGAG-3'
What is the sequence of the DNA coding strand? Of the DNA template
strand?
Translation. Write the anti-codon sequence of the MRNA transcript. Translate the
MRNA transcript into peptide sequence using both the 3 letter abbreviation and 1 letter
abbreviation.
