Practice question
Question
In Escherichia coli, the minimum number of crossovers required between F − genome and the linear DNA transmitted by Hfr to form a viable recombinant is _____. (Answer in integer) (NAT)
Explanation
Biologically, DNA replication fidelity operates via polymerase proofreading and origin firing ensure accurate duplication. Thus Option NAT is appropriate since it matches high-fidelity synthesis mechanisms, reinforcing core concepts taught in molecular biology.
