Summary Introduction
Introduction:
Recombination in bacteria results in the swapping of different genes amongst bacterial genomes. The two strains act as the parental genes and the recombinant strains differ from them in one or more genes. Such recombination can occur due to a conjugation where two bacteria join and swap genes.

- One advantage of using bacteria and viruses for genetic study is the fact that they have haploid genomes. Explain why a haploid genome facilitates genetic analysisarrow_forwarda. You have a test tube containing 5 ml of a solution of bacteriophages, and you would like to estimate the number of bacteriophages in the tube. Assuming the tube actually contains a total of 15 billion bacteriophages, design a serial dilution experiment that would allow you to estimate this number. Ideally, the final plaque-containing plates you count should contain more than 10 and fewer than 1000 plaques.arrow_forwardIn the Hershey and Chase experiment involving T2 phage,a. most of the 32P entered the bacterial cells whereas most of the 35S did not.b. most of the 35S entered the bacterial cells whereas most of the 32P did not.c. equal amounts of 32P and 35S entered the bacterial cells.d. none of the above was observed.arrow_forward
- why do the bacteria grow up to the edge of the area with antibiotics, pause, then continue to grow across the area with antibiotics? A) The antibiotics caused mutations in the DNA of the bacteria, making them resistant to the antibiotics. B) The bacteria mutated as a survival response to the presence of antibiotics, enabling the bacteria to become resistant to the antibiotics. C)A few bacteria experienced random mutations in their DNA, which allowed some of them to grow even though antibiotics were present. D) Researchers added antibiotic resistant bacteria to the culture, so that the bacteria would continue to grow across the area with antibiotics.arrow_forwardDescribe the experiment done by Frederick Griffith in 1928, where the non-lethal (rough) strain of Streptococcus pneumoniae bacteria killed experimental mice when mixed with the heat-killed smooth strain. Discuss what may have happened to the rough strain after the heat-killed smooth strain was introduced and why you think the rough strain killed the mice. What would be the conclusion and significance of this study and its finding?arrow_forwardThere have been recent outbreaks of dog flu in the US. Why doesn't this virus infect humans? A) The virus can replicate in cells of all species but can only egress from dog cells. B) The genetic code of the virus is the same as that in dog cells but is different from other organisms. C) The virus can only attach to dog cells. D) The virus can enter cells of all species but can only replicate in dog cells.arrow_forward
