In terms of lac operon regulation, what happens when E. coli is grown in medium containing no glucose but abundant lactose
Answer: Lactose is necessary for transcription process.
Explanation:
When there is no lactose provided to the E.coli molecule then the lac repressor cling to the operator, and it prevents the transcription process conducted by the RNA polymerase enzyme. But in the presence of lactose the lac repressor does not bind to the operator which allows the RNA polymerase to actually transcribe the lac operon.
When E. coli is grown in a medium containing no glucose but abundant lactose, then neither CAP nor the lac repressor are bound to the DNA.
The lac operon is a cluster of prokaryotic genes having a single promoter which is transcribed as a single polycistronic messenger RNA (mRNA) involved in using lactose as a source of energy.Moreover, the lac repressor is a protein that represses the transcription of the lac operon. When lactose concentration is too low, the lac repressor binds with the operator to prevent transcription.Catabolite activator protein (CAP) acts as a sensor of the glucose level.When glucose concentration is too low, then CAP binds to the promoter of the lac operon to produce this molecule.In conclusion, when E. coli is grown in a medium containing no glucose but abundant lactose, then neither CAP nor the lac repressor are bound to the DNA.

Frog's tongues are attached to the front of their mouths rather than at the back like humans. When a frog catches an insect it throws its sticky tongue out of it's mouth and wraps it around its prey. The frog's tongue then snaps back and throws the food down its throat.

Explanation:
Which mode of information transfer usually does not occur in a working human, plant or bacterial cell?
a.RNA to Protein
b.RNA to DNA
c.DNA to DNA
d.DNA to RNA
Answer: B. RNA to DNA
Explanation:
RNA to DNA mode of information transfer usually does not occur in a working human, plant or bacterial cell. The correct option is B.
Thus, Each human cell has two copies of the genetic material, which is spread among 23 pairs of chromosomes in the nucleus of each cell.
The human genome refers to all of this. There are about 30 000 genes in the human genome, and each one codes for a protein.
The human genome has long regions of transcribed DNA that do not code for proteins. Around 95% of the genome is made up of what are known as introns. Although the human genome's nucleotide sequence is now rather well established, we still don't fully comprehend why the majority of it is non-coding.
Thus, RNA to DNA mode of information transfer usually does not occur in a working human, plant or bacterial cell. The correct option is B.
