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.arrow_forward

Draw arrows connecting the concepts as appropriate, and label the arrows to indicate the relationship between those concepts. Typically, nouns will be the nodes of the map. Verbs and connecting ideas should be written on the connecting arrows. Illustrations of the central phenomena (replication, transcription, translation) are mandatory, and you must develop your own pictures. You can draw them by hand or use a computer illustrating program to draw, but you may not screenshot images from the internet.

You know that the virus is a single-stranded RNA virus, but you don’t know if it is plus or minus stranded. Your lab-mate says, “Well, just treat your cell culture with cyclohexamide and see if the virus replicates its genome.” You know that cyclohexamide inhibits protein elongation by binding to eukaryotic ribosomes.
