If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.

For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it pro

UNO [17]

Answer:

A,B and E

Explanation:

I+: I refers to the lac repressor, the + indicates that the repressor is functional

P+: P refers to the promoter region and the + indicates that the promoter is functional

Oc: O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.

Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional

Y+: Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional

So based on the breakdown above:

A is true because P+.

B is true because I+.

C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on) which is not the correct form.
