Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.

I wanna day C because let’s say you feed the mouse a piece a cheese and it gets a little be shiny but then when you feed it prices of hay it gets really shiny
If it contians 1/16th the amount, it must have gone through 4 half lives: 1> 1/2> 1/4> 1/8> 1/16>.since the half-life of c-14 is about 5730 years, the age of the fossil is 4 X 5730 years or about 22,920 years old.
