<u>Change in thermal energy and particle arrangement of molten steel after becoming completely solid:</u>

Due to the rise in the temperature, the particles start moving speedily. Because of the achieving the kinetic energy, which helps in the higher collision rate and makes the diffusion rate high. In case of the solids the particles are strongly bound in sequential order. Even though we can’t see it, but the vibrations can be felt. During heating the internal energy increases and helps the particle to move faster.

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.
