The lac operon is regulated by both the availability of lactose and glucose. How does E. coli regulate transcription of the lac operon?

E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).

Explanation:

The lac operon is regulated by both the availability of lactose and glucose. E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).

This cAMP acts a signaling agent which is made by E. coli anytime glucose levels are low In the cells which helps regulate the transcription process as glucose is needed for it .

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
