Principles of genetic technology — practice question
The first use of a technique for genetic engineering took place in 1973. Recombinant DNA was produced with the aid of a plasmid, and it was then transferred successfully into an organism.
A later technique for genetic engineering, known as gene editing, was created in 2012.
(a)[5]
Table 4.1 shows several statements about the two genetic engineering techniques.
Fill in Table 4.1 so that the original genetic engineering technique using a plasmid vector is compared with the newer technique of gene editing.
For every row, insert a tick (✓) in the appropriate column when the statement is true, and leave the space empty when it is not true.
