Describe the 4 combinations of active or inactive regulatory proteins that could be present at any time in the cell

1 answer:

8 0

The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.

The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:

1. Active repressor, active activator,

2. Active repressor, inactive activator

3. Inactive repressor, active activator

4. Inactive repressor, inactive activator

A restriction enzyme: Please choose the correct answer from the following choices, and then select the submit answer button.

Dimas [21]

Answer:

e. All of the above.

Explanation:

A restriction enzyme or restriction endonuclease is an enzyme that nicks or cuts DNA on a specific location after recognizing a specific sequence.
Restriction enzymes are widely used in cloning and biotechnological procedures.
The step of recombinant DNA technology requires the acquisition of the gene of interest (GOI). This is done by cutting it out of the donor genome.
Restriction enzymes perform this task by cutting on specific sequences. One important characteristic of restriction endonucleases is that they introduce "sticky ends" or overhangs in the donor sequence so it can be easily incorporated into the vector.

The cellular membrane across which ion flow varies during auditory transduction is the hair cell membrane.

<h3>What is a cellular membrane?</h3>

A cellular membrane separates the interior of all cells from the outside environment.

Lipids of cell membranes include phospholipids composed of glycerol, fatty acids, phosphate, and a hydrophobic organic derivative such as choline or phosphoinositol.

Thus, hair cell membrane is the correct answer.
