Part 1. Transduction is a form of horizontal gene transfer that involves viral infections. random mutation. physical contact between cells. acquisition of DNA from the environment.   Part 2:  Transformation is a mechanism of horizontal gene transfer that requires a virus to infect a cell. requires physical contact. transfers genetic information from parents to offspring. requires DNA to be present in the environment.

What is the function of DNA ligase? put DNA together are involved in transcription break down DNA fix the mismatch pairing are part of the ribosomes synthesis

Question 4 Why is CRISPR useful for genome editing? it can't be used in humans, but it works really well in most microbes it creates really long sticky ends that improve the efficiency of creating the correct plasmid it is being used to provide immunity to viruses in humans O it can direct DNA cutting to any specific sequence

What advantageous uses have viruses been shown to have? The activities of viral genes mimic those of host genes so they are useful for studying mechanisms of DNA replication and gene expression in their much more complex hosts. O Bacteria-killing viruses may play an increasing role in the war against bacterial pathogens. O All are correct. They can be used as a means to introduce foreign genes into human cells, which may serve as a basis for treatment of human diseases by gene therapy. O Insect-killing viruses may play an increasing role in the war against insect pests.
