(a(i))[2]
Identify the labels E and F in Fig. 6.1.
(a(ii))[1]
On Fig. 6.1, draw a circle round one nucleotide.
(a(iii))[1]
State the name of the covalent bond joining two nucleotides.
(b)[1]
Fig. 6.2 gives the RNA base sequence of a short primary transcript. Complete Fig. 6.2 by writing the DNA base sequence of the template strand that was used to make the primary transcript.
(c)[2]
In eukaryotic cells, the primary transcript is altered to produce mRNA. Explain how the primary transcript is modified to form mRNA.
(d)[5]
At the ribosome, the mRNA strand is translated to make a polypeptide. Describe how translation leads to the formation of a polypeptide.
