a)
Interpretation:
List the DNA sequences from which the RNA codons were transcribed.
AAU
Concept introduction:
The main function of messenger RNA (mRNA) is to give the direction to biosynthesis of thousands of diverse peptides and proteins required by organisms. The mechanics of protein biosynthesis take place on ribosomes, small granular particles in the cytoplasm of a cell that consist of 60% ribosomal RNA and 40% protein.
In
The sense and the antisense strand in DNA are complemetary to each other. The DNA antisense strand and the newly formed RNA strand are also complementary; the RNA molecule produced during transcription is a copy of the DNA sense strand. That is, the complement of the complement is the same as the original.
Note: The bounded amino acid sequence is always written from 5’→3’ direction. The codon sequences on mRNA are read by tRNA which are having complementary anticodon base.
Answer to Problem 27AP
The base sequence in the original DNA strand can be obtained as:
mRNA strand:
(5’)-AAU-(3’)
The antisense DNA strand will be the complement of mRNA:
Antisense DNA:
(3’)-TTA-(5’)
The base sequence in the original DNA strand can be obtained as:
Explanation of Solution
The original DNA sequence on which mRNA is formed is none other than antisense DNA. mRNA is a complement of antisense DNA which is formed by replacing (A by U, C by G, T by A and G by C).

The mechanics of protein biosynthesis take place on ribosomes, small granular particles in the cytoplasm of a cell that consist of 60% ribosomal RNA and 40% protein.
In DNA replication both the strands are copied. The DNA strand that contains gene is called coding strand or sense strand. The DNA strand which gets transcribed is called antisense strand or non-coding strand. During this process only one strand is transcribed into RNA strand.
