Document Summary
A: bacterial dna replication and transcription requires unzipping of the double. Does it supercoil to the point of not being transcribable? helix, which introduces supercoils. Without topoisomerase ii, bacteria can"t undergo replication and, as a consequence, can"t divide and grow (as a population). Your immune system takes care of the rest. Q3: is dna packaging analogous to the stretchy telephone cords? https://www. youtube. com/watch?v=k4fbpugkuri. Q4: how does the cell distinguish between single-stranded and double-stranded rna? those proteins that bind dsrna end up cutting it up. A: some proteins can only bind dsrna, others only ssrna (it"s a steric thing). A: exam question format will be similar to clicker questions & recitation questions. But a twisted rope is a better visual analog see animation here: A: we will cover that in nov 3rd lecture. Briefly: some of it is genes that code for functional rna units: ribosomal rna, transfer rna, microrna, etc.
