FEEDBACK: This is the functional definition of one certain type of gene. A gene is any DNA sequence that is transcribed into RNA. This includes mRNAs that encode proteins, but also RNAs that participate in protein synthesis (e.g., tRNAs and rRNAs) and other cellular activities.
1 Νοε 2017 · This theory, known as the ‘RNA world hypothesis’, posits that an RNA enzyme or ‘ribozyme’ capable of copying RNA molecules existed early in evolution, and that protein synthesis by the ribosome (which is also an RNA enzyme) evolved out of this system (Figure 1B; Gilbert, 1986; Atkins et al., 2011). The theory, however, is largely silent ...
