WebMar 14, 2024 · During elongation, the transcription machinery needs to move histones out of the way every time it encounters a nucleosome. Transcription elongation occurs in a bubble of unwound DNA, where the RNA Polymerase uses one strand of DNA as a template to catalyze the synthesis of a new RNA strand in the 5′ to 3′ direction. WebMay 7, 2024 · RNA is a small molecule that can squeeze through pores in the nuclear membrane. It carries the information from DNA in the nucleus to a ribosome in the cytoplasm and then helps assemble the protein. In short: DNA → RNA → Protein Discovering this sequence of events was a major milestone in molecular biology. WebRNA polymerase II is located in the nucleus and synthesizes all protein-coding nuclear pre-mRNAs. Eukaryotic pre-mRNAs undergo extensive processing after transcription but before translation. For clarity, the term “mRNA” will only be used to describe the mature, processed molecules that are ready to be translated. herbert von karajan biography
