Homework Answers
Transformation is the process in which a gene is transferred to a recipient cell (usually bacteria) from a donor cell or externally. The inserted gene gets incorporated into the chromosome of the recipient. The process of transformation is widely used in recombinant gene technology. This process also helps to create more strains of bacteria.
Transduction is the process of transferring genetic material into recipient cell externally through bacteriophages. Certain bacteriophages are used in this type of process. It helps in mapping genes. It causes many phenotypic and genotypic alterations in bacterial chromosomes.
Conjugation is the process in which genetic material is transformed through direct contact of bacterial cells horizontally. It results in exchanging of genetic information and results in diversity of bacteria. This method also helps bacterial evolution and help in developing into new strains.

13. Which of the following statements about conjugation is false? A) Conjugation is sexual reproduction for bacteria B) In conjugation a bacterium carries a fertility plasmid. C) In conjugation a bacterium forms a small hollow tube called a pilus. D) In conjugation a bacterium attaches to a neighboring bacterial cell that lacks a fertility plasmid. E) Conjugation can be a problem because fertility plasmids often carry genes that endow cells with drug resistance or the ability to produce toxins.

The giant sandworms of the planet Arrakis harbor a gut bacterium that undergoes conjugation. However, the conjugation lasts for 200 minutes. You perform an interrupted mating experiments and find that following markers are transformed at the respective times: ple 25 minutes, bar 75 minutes, gap 100 minutes, zap 150 minutes and chr 200 minutes. Draw a genetic map of the bacterium assuming a linear transfer rate of DNA. You also find that the plemarker is transferred at a higher rate...

What is the most common way that a bacterium can acquire a plasmid with genes for antibiotic resistance from another bacterium? O During sexual reproduction, the offspring receives chromosomes and plasmids from both bacterial parents. A bacterium can take up DNA (including plasmids) lost by another bacterium into its immediate environment through the process of transformation. O o Viruses can pick DNA (including plasmids) from one bacterium and transfer it to another bacterium by the process...

Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...
