Nettet6. jan. 2024 · As engineered polymerases achieve higher accuracy, other mutagenic sources start to become significant contributors to mutations in PCR products. For example, under Q5 cycling conditions, the amount of mutagenic DNA damage introduced during thermocycling was measured to be 1.4 × 10 −6 per base per PCR cycle, or once … NettetThere is a difference between CBR (of video) and system rate (or multiplexer rate). When video is encoded as CBR, say at 3.2 Mbps, it is quite ok that it fluctuate by a few hundred kbps around that margin. So peak bitrate, could be say 3.3 Mbps. This is quite ok. Adding another 100 kbps of Audio, the total maximum bitrate can be 3.4.
