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 gallop is the fastest gait of the horse, averaging about 40 to 48 kilometres per hour (25 to 30 mph). The speed of the canter varies between 16 and 27 kilometres per hour (10 and 17 mph) depending on the length of the stride of the horse. A variation of the canter, seen in western riding, is called a lope, and generally is quite slow, no more than 13â19 kilometres per hour (8â12 mph).
