The trp and lac operons are regulated in various ways. how do bacteria regulate transcription of these operons?
Vlada [557]

Operon is not transcribed:

-lac operon: lactose absent

-trp operon: tryptophan present

Positive control transcription of Operon does not speed it up:

Lactose and glucose are present, -lac operon

Tryptophan is lacking in the -trp operon.

Operon is transcribed quickly through positive control:

-lac operon: lactose present, glucose not

Only negative control is used to regulate the trp operon. The operon genes are not transcribed when tryptophan is present.

Both positive control and negative control are used to control the lac operon.

Negative control: —Transcription is inhibited when lactose is missing due to the activity of the repressor protein.

—The repressor protein is deactivated and transcription is triggered when lactose is present.

Positive control: —In the absence of glucose, another regulatory protein (CAP) attaches to the lac operon's promoter, speeding up transcription in the presence of lactose.

Skin is able to prevent most microorganisms from entering the body by
Goshia [24]
The structure of the skin is an effective barrier against bacteria. The multiple layers of epidermis, while can be invaded by foreign organisms, has a high turnover rate which means it is constantly shedding, therefore even the bacteria is shed protecting the body. Lastly, the skin's lipids maintain an acidic pH which slows and stops growth and replication of bacteria.
