Concept explainers
(a)
Interpretation:
For the given DNA template strand, 5’-ATCTACCGTTA-3’, the sequence for the mRNA molecule needs to be determined.
Concept introduction:
mRNA sequence is the coding of genes as well as an amino acid. In transcription and replication, this sequence is used.
(b)
Interpretation:
For the given mRNA base sequence 5’-UUGCCUAGUGAUUGGAUG-3’ by assuming reading fame starts from 5’ end. The amino acid sequence that can be formed needs to be determined.
Concept introduction:
mRNA sequence can be determined based on Condon chart.
(c)
Interpretation:
The sequence of the polypeptide formed due to the addition of poly (UUAC) to a cell-free protein-synthesizing system needs to be determined.
Concept introduction:
The sequence of the protein can be given by DNA which encodes a protein and also change in DNA sequence will change the amino acid sequence of proteins.

- carbons in each of the structures below. For instance, the central carbon of chloromethylbutane (pictured 3. A chiral carbon is a carbon that is single-bonded to four different types of groups. Identify the chiral above) is a chiral carbon. (Can you see how the groups attached to it are all chemically different?)
