Describing mechanisms of genetic regulation

In this lesson, we are trying to understand the mechanism of genetic regulation in case of this particular genetic switch. Let's describe it as we understand it.

Questions

Please answer the questions below.

When there are changes in the external environment in terms of presence or absence of certain sugars, different proteins are produced. This is called ‘genetic regulation’ of protein production. How is this achieved in the cell?

How is it related to the energy changes of the cell?

We have observed how a cell responds differently in terms of protein production to the presence or absence of lactose or glucose in the environment. Molecular biologists refer to this as a Genetic Switch. Can you think of a reason why? Can you explain why it is a genetic switch?

What is one big idea that you learned in this unit so far? Explain in detail.
