Basketball the basketball is also regulated. For men, the official ball is in circumference (size 7, or a "295 ball") and weighs 22 oz (623.69 grams). If women are playing, the official basketball size is in circumference (size 6, or a "285 ball") with a weight of 20 oz (567 grams). In 3x3, a formalized version of the halfcourt 3-on-3 game, a dedicated ball with the circumference of a size 6 ball but the weight of a size 7 ball is used in all competitions (men's, women's, and mixed teams). The ball may be advanced toward the basket by being shot,
Molecular-weight size marker On the other hand, the size of the DNA pieces are based on the sites where the restriction enzyme cuts. This makes it more difficult to control the size of the fragments in the marker. More recently, another method for constructing DNA molecular-weight size markers is being employed by laboratories. This strategy involves the use of Polymerase Chain Reaction (PCR). This is achieved one or two ways: 1) a DNA target is amplified at the same time via primer sets, or 2) different DNA targets are amplified independently via particular primers. As with experimental samples, the conditions of the gel
