Principles of genetic technology — practice question
In 1973, a genetic engineering method was employed for the first time. Recombinant DNA was produced with a plasmid, and this was then successfully introduced into an organism.
By 2012, a different genetic engineering method, known as gene editing, had been developed.
(a)[5]
Table 4.1 contains several statements about the two genetic engineering techniques.
Complete Table 4.1 by comparing the earlier genetic engineering method that uses a plasmid vector with the newer gene editing method. In each row, put a tick (✓) in the column where the statement applies and leave the other column empty if it does not.

Identify the letter that shows the wild type orange trees in Fig. 4.1.
(b(ii))[3]
Explain the social benefits of this example of gene editing.
