The trp and lac operons are regulated in various ways. How do bacteria regulate transcription of these operons? Sort the stateme

OLEGan [10]

Answer:

Operon is not transcribed:

-lac operon: lactose absent

-trp operon: tryptophan present

Operon is transcribed, but not sped up through positive control:

-lac operon: lactose and glucose present

-trp operon: tryptophan absent

Operon is transcribed quickly through positive control:

-lac operon: lactose present, glucose not

Explanation:

The trp operon is controlled via negative control only.

Presence of tryptophan will inhibit the transcription of the operon genes

The lac operon is controlled via negative control and positive control.

●Negative control:

--Transcription is turned off due to

active Repressor protein and absence of lactose

--Transcription is turned on due to

Inactive Repressor protein and presence of lactose

●Positive control:

--Transcription rate is higher due to absence of transcription and presence of lactose as a regulatory protein (CAP) adhere to the lac operon promoter

Select the correct statement about bacteria.

kompoz [17]

Answer: C. Certain bacteria live within rocks kilometers below the Earth’s surface.

Explanation:

Bacteria are microscopic, usually single-celled living organisms that can be found in many environments. The live in practically anywhere on the planet because they are able to adapt to environmental changes. Bacteria regulate changes or modifications to their cell envelope in a coordinated way, allowing them to survive in different environments.

The main difference between bacteria and other cells is that bacteria are cells that do not contain a nucleus or other membrane-bound organelles.

These organisms can live in soil, the ocean and also inside the human gut. They can be dangerous, for example, when they cause infections they are able to injure different cells and tissues and compromise the immune system. On the other hand, most of the time they are beneficial, as in the process of fermentation such as in wine or yougurt, or helping with the digestion.
