Overview of Transcription Transcription factors are? This is just one example of how a cell can convert a source of information into a change in gene expression. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines. Edit. Post-transcriptional modification or co-transcriptional modification is a set of biological processes common to most eukaryotic cells by which an RNA primary transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell. 27 Related Question Answers Found How do transcription factors regulate gene expression?

Transcription factors control when, where, and how efficiently RNA polymerases function. DNA → RNA → Protein. The process relies on Watson-Crick base pairing, and the resultant single strand of RNA is the reverse-complement of the … Like prokaryotic cells, the transcription of genes in eukaryotes requires the action of an RNA polymerase to bind to a DNA sequence upstream of a gene in order to initiate transcription. These viruses cause cancers in animals, hence known as oncogenic. However, unlike prokaryotic cells, the eukaryotic RNA polymerase requires other proteins, or transcription factors, to facilitate transcription initiation.
