二、判断
1、Polynucleotides (DNA and RNA) contains: (deoxy)ribose, phosphoric acid; bases
2、Bases includes:
Two purines: adenine and guanine (腺嘌呤和鸟嘌呤)
Three pyrimidines: cytosine, uracil, thymine (胞嘧啶、尿嘧啶和胸腺嘧啶)
3、DNA is the genetic material of organisms.
(1)Nucleic acids absorb UV light at 260nm because of the electronic structure in their bases.
(2)but when two strands of DNA come together, the close proximity of the bases in the two strands quenches减弱 some of this absorbance. 减色效应
(3)When the two DNA strands separate, this quenching disappears and the absorbance rises 30-40%.增色效应
