The diagram shows a yeast cell.

Biofuel is made from ethanol.
Scientists use genetically modified (GM) yeast to produce biofuel.
The GM yeast contains an enzyme that digests plant cell walls to produce glucose.
The yeast uses the glucose in respiration to produce ethanol.
The GM yeast is a recombinant strain.
State what is meant by the term recombinant.
contains new DNA / new gene / foreign DNA / foreign gene / altered genes / DNA from other
organism/ DNA from other species / gene from other organism / gene form other species /
contains gene for digesting cell walls / contains gene for digesting cellulose / gene for cellulase / eq /
