Choose the correct type of expression for each example.

Inducible, Constitutive, or both?

An enzyme that breaks down sucrose is only expressed in the presence of sucrose.

  Inducible, Constitutive, or both?

An enzyme is continuously produced regardless of the chemical makeup of the environment.

  Inducible, Constitutive, or both?

A researcher wants to have an enzyme produced in a bacteria that he can turn on at a specific time, which type of promoter should he choose?

  Inducible, Constitutive, or both?

A researcher wants to express a protein in a plant at the same level regardless of the stage of life or nutrients present, which type of promoter should he use to express that gene?

Situation Answer

1. An enzyme that breaks down sucrose is only expressed in the presence of sucrose Inducible

Explanation: The enzyme which breaks down sucrose is activated when sucrose is present which means it is a inducible enzyme , which is induced by sucrose and it is not expressed when sucrose is absent.

2. An enzyme is continuously produced regardless of the chemical makeup of the environment Constitutive

  Explanation: An enzyme which is continuously expressed regardless of the environment is constitutive because it is not induced or repressed by any external factors. It remain expressed condition irrespective of the situation.

3. A researcher wants to have an enzyme produced in a bacteria that he can turn on at a Inducible   

specific time, which type of promoter should he choose?

Explanation: the researcher should choose a inducible promoter to control the gene expression. When he will add the inducer, the gene turn on and when he withdraw the inducer, the gene remain in turned off phase.

4. A researcher wants to express a protein in a plant at the same level regardless of the Constitutive

stage of life or nutrients present, which type of promoter should he use to express that gene?   

Explanation: The researcher if want the gene t be expressed all the time at the identical level, he should use a constitutive promoter which will not be affected by the nutrient . If a gene is under constitutive promoter, it will be under constitutive promoter.
