What is the main idea associated with BAC?

Answer and explanation

Correct answer: Bacterial artificial chromosome

BAC stands for bacterial artificial chromosome. It is an engineered DNA molecule derived from bacterial chromosome elements and is used as a cloning vector in a bacterial host. Its major value is that it can carry comparatively large foreign DNA inserts while remaining maintained in the host cell. Therefore, the expansion of BAC is not related to amino acids, chlorophyll, amylase, bones, or calcium. Option A is correct because it gives the standard biological meaning of the abbreviation and identifies the vector type. The other options are invented phrases and do not describe any recognized recombinant-DNA vehicle or chromosome-based cloning system.
