DNase agar is a differential medium that tests the ability of an organism to produce an exoenzyme, called deoxyribonuclease or DNase, that hydrolyzes DNA.DNase agar contains nutrients for the bacteria, DNA, and methyl green as an indicator.Methyl green is a cation which binds to the negatively-charged DNA.Nase agar is a differential medium that tests the ability of an organism to produce an exoenzyme, called deoxyribonuclease or DNase, that hydrolyzes DNA.
In 1959, the NCAA goalposts were widened to 23 feet 4 inches (7.11 m), the standard width for high school posts today. In 1991, the college goalposts were reduced in width to 18 feet 6 inches (5.64 m), matching the width of NFL goal posts. For the 1991 and 1992 seasons, this meant potentially severe angles for short field goal attempts, since the hashmarks were still located 53 feet 4 inches (16.26 m) apart.
A recent rule change means NFL goal posts, such as this one at the Superdome in New Orleans, must be 35 feet tall instead of 30 feet. The NFL's decision last week to increase the height of its goal post uprights, from 30 feet to 35 feet, wasn't a big deal to most of us. Just weld or duct-tape another 5 feet of pipe to each side, right? Turns out, it's not that easy, according to folks in the business of manufacturing goal posts.
