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.
The Best Bikes of 2015-2016 >>>. There are plenty of ways to enjoy a warm spring afternoon, but riding a bike is one of the most active ways to spend your leisure time. According to NutriStrategy, a relaxing bike ride (<10 mph) burns more calories than an easy walk (2 mph)â281 calories versus 176 calories per hour. Challenge yourself by powering your way up hills and pushing your speed over 10 mph, but even keeping to a leisurely pace is a great way to supplement an active lifestyle.
I know a bunch of cyclists...they do an average of 30 miles on their daily rides. I usually ride for time, not mileage. A short ride for me is maybe 1 1/2 hours. A long ride is at least 4-6. I do a couple of short rides per week, two mid-range (2-3 hours) and a least one long.
