Which of the following is true of in vitro evolution?
A) In vitro evolution refers to bioprospecting for naturally occurring macromolecules.
B) In vitro evolution can produce new molecular sequences not known from nature.
C) In vitro evolution can only produce new proteins.
D) In vitro evolution only selects for changes that were present in the starting pool of molecules, and does not introduce any new mutations.
E) All of the above

Question

Quizplus · Accepted Answer

In vitro evolution involves generating a large pool of random molecular sequences and selecting for those that possess a desired activity or function. By subjecting these selected molecules to further rounds of mutation and selection, it is possible to generate entirely new sequences that were not present in the original starting pool of molecules. Therefore, option B is true while options A, C, and D are false.
