WebFeb 12, 2024 · In prokaryotes, polycistronic expression is common. Prokaryotic genes, usually with a shared function or pathway, are clustered into operons that are cotranscribed to generate polycistronic mRNAs. Similarly, mitochondria and plastids, which evolved from prokaryotes, express many of their genes on polycistronic transcripts. WebThe Central Dogma. Francis Crick coined the phase “the Central Dogma” to describe the flow of information from nucleic acid to protein. Information encoded in DNA is transcribed to RNA, and RNA is translated to a linear sequence of amino acids in protein. Although information can flow reversibly between DNA and RNA via transcription and ...
