How is it beneficial for organisms to control gene expression

Asked by admin @ 22/11/2021 in Biology viewed by 337 People

Regulation of gene expression helps organisms adjust to their environment. Single-celled organisms are directly exposed to their environment when it changes. In terms of regulation of gene expression, how do these single-celled organisms deal with their changing environments?

Answered by admin @ 22/11/2021

Answer:

To deal with their changing environments, the single-celled organisms develop adaptation mechanisms.

Explanation:

All cells have the means to adapt to the changes that occur in their surrounding space, especially since this changes all the time.

In order to realize these changes, each cell had to produce a modification in its biochemical composition. Among them are the changes produced in the enzymatic molecules, either in their activities or in the rates of synthesis of the new molecules.

Initially, the detection of changes in the environment was detected within each cell, allowing the detected chemicals to bind directly to the proteins found in the cells, allowing them to modify their activity.

Later, more mechanisms were developed to recognize these changes, without the need for chemicals to enter the cell.

But this time, it was the proteins that joined the chemicals, and this caused the structure of the protein to change.

All multicellular organisms began being single-celled, where they only interacted with each other to compete for resources. But then they evolved to form colonies, which contained cells that interacted together being differentiated cells.

Through this process, the cells were able to create responses to changes in the environment and through complex gene expression processes they will be able to form a complex organism.
