Which cluster of terms accurately reflects the nature of DNA replication in prokaryotes?
A) fixed point of initiation, bidirectional, conservative
B) fixed point of initiation, unidirectional, conservative
C) random point of initiation, bidirectional, semiconservative
D) fixed point of initiation, bidirectional, semiconservative
E) random point of initiation, unidirectional, semiconservative

Question

Quizplus · Accepted Answer

Prokaryotic DNA replication starts at a fixed point of initiation, proceeds bidirectionally and is semiconservative, meaning each daughter cell gets one old and one new strand of DNA. Option A is incorrect as prokaryotic DNA replication is not conservative, i.e., it does not preserve the parental DNA molecule intact. Option B is incorrect as prokaryotic DNA replication is bidirectional. Option C is incorrect because although prokaryotic DNA replication starts at a fixed point, it is not random in its initiation. Option E is also incorrect as prokaryotic DNA replication is bidirectional.
