Question

Each statement describes a type of gene regulation. Determine if it describes regulation at the transcription, translation or post-translation level.

1. Genetic regulatory proteins bind to the DNA. Transcription / Posttranslation / Translation
2. A transcription terminator forms in the RNA. Transcription / Translation / Posttranslation
3. Repressor proteins bind to an mRNA and prevent ribosome binding.Translation / Posttranslation / Transcription
4. Riboswitches produce an RNA conformation that prevents ribosome binding. Posttranslation/ Translation/ Transcription
5. Antisense RNA binds to the mRNA.Translation / Transcription / Posttranslation
6. The product of a metabolic pathway inhibits the first enzyme in a pathway.Posttranslation/ Transcription/ Translation
7. A protein is covalently modified. Posttranslation / Translation / Transcription

Answer 1

1. Gene regulatory proteins bind to the DNA at transcription level.

2. A transcription terminator forms in the RNA occurs at Transcription level.

3. Repressor proteins bind to an mRNA and prevent ribosome binding occurs at transcriptional level.

4. Riboswitches produce an RNA conformation that prevents ribosome binding occurs at Translation level.

5. Antisense RNA binds to the mRNA occurs at the level of Transcription.
6. The product of a metabolic pathway inhibits the first enzyme in a pathway occurs at Translation level.
7. A protein is covalently modified is a Posttranslation modification.
