The Associative Laws say that it doesn't matter how we group the numbers (i.e. which we calculate first) ... ... when we add : (a + b) + c = a + (b + c). ... or when we multiply : (a Ã b) Ã c = a Ã (b Ã c).
To complete the PCT in two months (or less) you will need to average approximately 43.6 mi / 70.2 km per day (this was my longest day on trail).
In a single polymerase chain reaction (PCR) cycle consisting of 15 seconds at 94Â°C, 30 seconds at 50Â°C, and 1 minute at 72Â°C, what is happening in the step run at 50Â°C? Primers are annealing to the DNA to be amplified.
