- what’s a plasmid?Can a bacteriophage infect a human?An E. coli colony grew on minimal medium supplemented with arginine and leucine. However, bacteria from this colony are unable to grow and form colonies on minimal medium supplemented with arginine and methionine. What is the genotype of the bacteria in this E. coli colony?
- Who discovered the plasmids?1 mL of a bacteriophage suspension is mixed with 20 mL of a bacterial culture and 50% of the phages adsorb. We know that the bacteriophage suspension had a concentration of 1x1010 viruses per mL, and the bacterial culture had a concentration of 3x108 bacteria per mL. What fraction of the cells is multiple infected?To which phage types was this strain of S. aureus susceptible?
- If you extract the DNA of the coliphage φ X174, you willfind that its composition is 25 percent A, 33 percent T,24 percent G, and 18 percent C. Does this compositionmake sense in regard to Chargaff’s rules? How wouldyou interpret this result? How might such a phage replicate its DNAOne mL of a bacteriophage suspension is mixed with 20 mL of a bacterialculture and 50% of the phages adsorb. We know that the bacteriophagesuspension had a concentration of 1x10^10 viruses per mL, and the bacterialculture had a concentration of 3x10^8 bacteria per mL. What fraction of the cells is single infected?One mL of a bacteriophage suspension is mixed with 20 mL of a bacterialculture and 50% of the phages adsorb. We know that the bacteriophagesuspension had a concentration of 1x10^10 viruses per mL, and the bacterialculture had a concentration of 3x10^8 bacteria per mL.
