Genetic modification — practice question

Genetic engineering is one instance of an important biotechnology.
(a)[9]

Complete the passage below by filling each gap with a suitable word. DNA is a biological molecule located in the [BLANK] of an animal cell. The order of the [BLANK] in mRNA controls the sequence of amino acids that will be assembled into a [BLANK]. In genetic engineering, fragments of human DNA called [BLANK] are cut using restriction enzymes. Bacterial plasmids are then cut with the [BLANK] restriction enzymes to produce complementary [BLANK] ends. The piece of human DNA is inserted into the cut plasmid and the two are joined to make a [BLANK] plasmid. These plasmids are placed into [BLANK], where replication happens. This technique is used to make human [BLANK] for the treatment of diabetes.

(b)[2]

State two examples of how enzymes are used in another biotechnology, apart from genetic engineering.
