A nice bell-like shape of count distribution is observed after this filtering of noise. Line colors decode individual samples. WebProteins are the key working molecules and building blocks in all cells. They are produced in a similar two-step process in all organisms called protein synthesis – DNA is first transcribed into RNA, then RNA is translated into protein. Upstream of individual genes, sequences of DNA called promoters determine when proteins are produced and in ...
