The table below shows the percentage of bases in each of the strands of a DNA
molecule.

strand base

A C G T

Strand 1 16

Strand 2 21 34


(b) Complete the table by adding the missing values.
(2)




(c) During replication, the two DNA strands separate and each acts as a template for
the production of a new strand. As new DNA strands are produced, nucleotides can
only be added in the 5’ to 3’ direction.

Use the figure in part (a) and your knowledge of enzyme action and DNA replication
to explain why new nucleotides can only be added in a 5’ to 3’ direction.
