ILING GENE EXPRESSI OVERVIEW: Exact, yet variable and mutable - these are the characteristics of our (deoxyribonucleic acid). DNA is composed of subunits called nucle to form long polynucleotide strands. When nucleotides in one strane hydrogen bon heliv PCB 3063L. (a)Given the following DNA molecule, write the sequence of the messenger RNA synthesized from the upper strand. [I] 3" TACGGTAAAACT 5* 5" b) Indicate the 5' and 3' ends of the message. [1] c) Groups of three letters on the mRNA molecule are calledIl d) What is the special significance of the first group of three letters in the message? [1] e) What is the special significance of the last group of three letters in the message? [UI . (a) In the diagram, label the indicated parts. site site b) Label the 5 and 3' ends of the messenger RNA in the diagram. on of the correct amino acid into aExplanation / Answer
1. a&b
5' AUGCCAUUUUGA 3'
c. codon
d. They are known as a start codon. It is AUG from where translation will start.
e. stop codon they stop the translation.
2. The lower subunit is the smaller subunit.
the upper subunit is the larger subunit.
From where a new codon comes is A site and from where it leaves is E site.
