Which of the following is the best way to genetically modify a cell?
A) transformation
B) ligation
C) plasmid cleavage
D) isolation of gene
E) restriction-enzyme digestion of gene
Which of the following enzymes converts RNA into DNA?
A) DNA polymerase
B) ligase
C) RNA polymerase
D) reverse transcriptase
If you put a gene in a virus, the next step in genetic modification would be
A) insertion of a plasmid
B) transformation
C) transduction
D) PCR
Answer (2)
Transformation modifies a cell by taking up external DNA, reverse transcriptase is key in converting RNA into DNA, and transduction involves introducing genes via viruses. ;
Transformation is the preferred method for genetically modifying cells, as it allows them to uptake foreign DNA. Reverse transcriptase is the enzyme that converts RNA to DNA, and transduction is the process of introducing genes through viruses.
