Solution Summary

The expert describes the importance of consensus sequences. The events that occur in transcription and sigma are determined.

Solution Preview

A consensus sequence is a series of nucleotides that confers a certain function in the DNA strand. It allows one to predict sites of interaction with various transcription factors or endonucleases. For example, the restriction endonuclease BamHI recognizes the GGATCC consensus sequence. These sites are important because they allow us to predict what kinds of regulation a gene might experience at the transcriptional ...
