Reverse transcriptase is the viral enzyme responsible for making a DNA copy of the RNA genome from a retrovirus. As such, it is technically known as an RNA-dependent DNA polymerase. This is opposite to the usual flow of genetic information from DNA to RNA to protein.
This means downhill sections of the ride may be faster, and uphill sections slower. 1  Easy: Under 10 mph. 2  Leisurely: 10-12 mph. 3  Steady: 12-14 mph.  Moderate: 14-16 1  mph. Brisk: 16-18 2  mph. Vigorous: 18- 20 3  mph. Strenuous: 20-22  mph. Super Strenuous: 22+ mph.
Most walks you'll do will fall into one of three categories: slow paced (relaxing) 50-60 spm, medium paced (aerobic conditioning) 60-70spm, or fast paced (cardiovascular conditioning)70-80 spm. First, find out what your current slow pace cadence is. To do this, take your metronome with you on your next walk.
