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.
The total distance covered by a horse in a day will be determined largely by the pace that you set for the ride. A horse's speed depends on gait: Walk: 4 mph Trot 8 to 12 mph Canter 12 to 15 mph Gallop 25 to 30 mph. A typical horse may be comfortable walking for eight hours, meaning he could cover 32 miles in that time. Many weekend-warrior riders can't stand eight hours in the saddle, though.
