Document Summary

1. dna directs the functioning of living cells and is transmitted to offspring. 2. mechanism for decoding genetic information and directing cellular processes begins with rna synthesis (transcription). 3. several types of rna participate in the synthesis of enzymes, structural proteins, and other polypeptides necessary for organismal function (translation). 4. gene expression is the set of mechanisms whereby cells control the timing of gene product synthesis in response to environmental/developmental cues. Updated version: computer program vs. genetic information computer program is a more predictable process, the genetic information and regulation is far more complex and dynamic living! Central dogma states that dna is transcribed to rna which is translated to protein. We now expand that to include more features of what is taking place in a cell. We know rna can influence transcription of other rna molecules (not all rna is used to make protein). We also know that proteins can influence transcription and translation processes.
