Question

Eukaryotes 1. describe the current model for progressive levels of DNA packing (i.e. nucleosomes – 30nm fibers, looped domains….). 2. explain the potential role that activators, repressors and promoters play in transcriptional control. 3. describe the importance of mRNA degradation in eukaryotes. 4. explain how gene expression (protein synthesis) may be controlled at the translational and post-translational level.

Step 1

Activators are proteins that bind to specific DNA sequences and enhance transcription by recruiting RNA polymerase and other transcription factors. Repressors, on the other hand, inhibit transcription by blocking the binding of activators or RNA polymerase. Show more…
