Table 6.1 lists some characteristics of an antibody molecule and a haemoglobin molecule. Complete Table 6.1 so that it becomes a summary of the features of the two molecules.
(b)[2]
The base sequence in Fig. 6.1 is a short section of a longer DNA strand that is transcribed to make mRNA. When it is translated, this short section gives the amino acid sequence threonine (Thr), proline (Pro), cysteine (Cys). Complete the two unshaded boxes in Fig. 6.1 to show: • the mRNA codon for Cys • the tRNA anticodon for Thr. You do not need to enter the codon and anticodon sequences in the shaded boxes.
