Which situation would most likely result from a mutation in the ori gene of a bacterial cell?
A) The cell would not be able to detect whether conditions were favorable for replication.
B) The initiation of DNA replication would be hindered.
C) DNA replication would be prolonged abnormally.
D) The cell would not be able to segregate DNA molecules.
E) The cell could not undergo meiosis.

Question

Quizplus · Accepted Answer

The ori gene is responsible for initiating DNA replication in bacterial cells. A mutation in this gene would likely hinder the initiation of DNA replication, resulting in the inability to properly replicate the DNA. Therefore, option B is the best choice. Option A is incorrect because the ori gene is not involved in detecting favorable conditions for replication. Option C is incorrect because a mutation in the ori gene would not necessarily prolong DNA replication. Option D is incorrect because the segregation of DNA molecules occurs after replication, not during initiation. Option E is incorrect because bacterial cells do not undergo meiosis.
