1.) What does RNA polymerase do in transcription? 2.) What is the end product of transcription? The tRNA molecule binds a start codon of the mRNA molecule during: A) elongation. B) initiation. C) transcription. D) termination. Which site in mRNA facilitates the correct positioning of ribos...
If the DNA strand shown below is used as a template for RNA polymerase, what would be the sequence of the resultant mRNAfollowing transcription? 5'-CATTCCATAGCATGT-3' A. 5'-UGUACGAUACCUUAC-3' B. 5'-CAUUCCAUAGCAUGU-3' C. 5'-GUAAGGUAUCGUACA-3' D. 5'-ACAUGCUAUGGAAUG-3' 相...
Does RNA polymerase unwind DNA? What happens during the elongation step of DNA transcription? What is RNA polymerase? What is the role of RNA polymerase? What does DNA polymerase do when it meets a promoter? What happens next after the ribosome reaches the start codon?
These include covalent modifications of chromatin, structural changes and modulation of RNA polymerase II activity. Mechanisms of silencing and activation antagonize each other. During the cell cycle, replication and mitosis are the stages at which epigenetic memory is most likely to be erased. Each ...
These RT-PCR (real-time polymerase chain reaction) tests are much more sensitive than HIV tests used in the past. They can find as few as 20 copies of HIV RNA in a milliliter of blood. Your doctor should use the same HIV viral load test each time because tests made by different manuf...
In the future, if the same virus invades again, the bacterial cell now has a complementary RNA sequence which recruits the Cas nuclease to cut the viral DNA and stop the infection. But with this system in place, how does the viral genome fragment embedded in the bacterial genome not trigger...

During replication, the virus does not heavily rely on the enzymes of the host. As such, they carry their own RNA-dependent RNA polymerase with the replication cycle taking place in the cytoplasm (this is because they do not need elements of replication located in the nucleus). ...
Rather, reductionist approaches suggest that each module can function independently of the others in gene regulation. However, the evolutionary conservation of SAGA composition argues for the importance of associating different activities, which appear to synergistically control global RNA polymerase II-...
