Students have asked these similar questions
You are tutoring a fellow student about the genomes of prokaryotes. You ask them to give you one important characteristic about the genomes of bacteria. Which of the following statement given by your student is correct?
-Bacterial cells can contain DNA called plasmids.
-The bacterial chromosome is not contained within a nucleus but, rather, is found at the nucleolus
-Bacterial genomes are diploid throughout most of the cell cycle.
-Bacterial genomes are composed of linear DNA.
-Bacterial cells have multiple chromosomes, "packed" with a relatively large amount of protein.
What is a genophore?
A
DNA in prokaryotes
B
DNA and RNA in prokaryotes
C
DNA and protein in prokaryotes
D
RNA in prokaryotes
Imagine that there is an E. coli outbreak in your area, and you would like to test the kangkong from your local grocery store. How could you modify this protocol to extract DNA from the kangkong (to identify the species) and check for presence or absence of E. coli.? Keep in mind that (i) E. coli is free-living and not an endosymbiont, and (ii) plant cells are encased in both a cell membrane and cell wall.

References:arrow_forwardYou are working with E. coli, studying its metabolism. Your normal lab strain of E. coli can grow using any 6-carbon sugar (glucose, fructose, etc) as its sole carbon and energy source. Recently you have generated a mutant of your E. coli that cannot grow on fructose as its sole carbon and energy source. It can still grow using glucose or other 6-carbon sugars as a sole carbon and energy source. What is the most likely hypothesis for what single gene has been mutated in your new E. coli strain?
