eukaryotic gene regulation: \\ Transcription factors are sometimes activated by phosphorylation as in the MAPK pathway. Explain how this links an extracellular hormone signal to eukaryotic gene transcription. Be specific. Which transcription factor becomes translocated to the nucleus downstream of calmodulin...
Explain the regulation of gene expression in eukaryotic cells. What are the types of transcription activators in eukaryotes? Which of the following is characteristic of genes and gene regulation in bacteria, but not in eukaryotes? a) presence of enhancers b) capping of mRNAs c) many chro...
What is gene regulation in prokaryotes? What is the main difference between a cell nucleus and a nucleoid? What is the difference between ribosomes and ribosomal DNA? Do prokaryotes have ribosomal RNA? What are prokaryotic and eukaryotic cells?
which tells the cell how to make proteins, and ribosomes, which make the proteins, the manner in which the cell does this depends on whether the cell is prokaryotic or eukaryotic. The prokaryotic ribosome
The short answer to your second question is no, transcription generally does not happen at the same time as DNA replication. In eukaryotic cells, DNA replication occurs during the S-phase of the cell cycle. During S-phase, RNA transcription and protein translation are largely limited to the ...

19K Gene expression initiates gene regulation which allows DNA to be turned on and relay instructions to the cell so that it knows what to do next. Study the techniques for analyzing gene expression, including mRNA detection and DNA detection. Related...
