Question of the day

True/False: In the presence of tryptophan, transcription of the trp operon is on.

Regulation of the trp operon is a repressible system. When tryptophan is present, it binds to the repressor protein to form an active repressor that attaches to the operator and blocks RNA polymerase, preventing transcription of the operon. This negative feedback stops production of more tryptophan when it’s already available. Only when tryptophan is scarce does the repressor become inactive, allowing transcription to proceed. So transcription is not on in the presence of tryptophan; it’s turned off.

    After finishing the DNA Biology Practice Test, I felt a huge confidence boost. The explanations tie back to core concepts like DNA replication, gene regulation, and mutation types. The flash cards lock in terminology, and the randomized questions felt surprisingly like what I’ll see on exam day. Solid prep on Examzify.

    Coming up to the big day, I’m glad I found Examzify. The randomized set means I won’t see the same questions twice in one session, which keeps me honest. Explanations are detailed, and the content aligns well with class studies. A solid addition to my prep toolkit.

    Decent, but not perfect. Some questions feel similar to those from other materials, which is fine, but I wish for more variety in how topics are tested. The explanations are okay, and the randomization helps, yet I still want deeper synthesis practice before the actual exam.
