DNase Test. 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.
It is interesting that the size of the type is so small that you cannot read it unless you are about 25 feet away. 300 feet is the length of a football field from goal post to goal post. I have never noticed this much open space behind an emergency vehicle even though it is easy to read at a close distance.
