1.【化】鸟嘌呤
1.a purine derivative that is one of the four bases in DNA and RNA.
1.consequently they are commonly referred to simply by their purine or pyrimidineoriginal base components adenine, cytosine, guanine, thymine.
因此，他们通常被称为只要他们嘌呤或嘧啶在原有的基础上组成部分腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶。
2.Guanine shows up on product labels as CI 75170, or to give the more beautiful label bestowed on it, natural pearl essence.
鸟嘌呤在产品标签上标示为“C175170”，或者美名其曰为“天然的珍珠精华”。
3.In DNA, four different bases are found. Two of these, adenine and guanine, are double-ring structures called purines.
在DNA中，有四种不同的基，其中的两个为腺嘌呤和鸟嘌呤，即称为嘌呤的双环结构。
4.The single mutation in the earwax gene is one in which a G (for guanine) is replaced with an A (for adenine).
耳垢基因的单链变异是因为DNA链上的A（腺嘌呤）取代了G（鸟嘌呤）。
5.DNA consists of a chain made from four types of nucleotide subunits: adenine, cytosine, guanine, and thymine.
的DNA链组成一个由4种核苷酸亚基：腺嘌呤，胞嘧啶，鸟嘌呤和胸腺嘧啶。
6.Under normal conditions, a guanine matches with a cytosine, and an adenine with a thymine.
在正常情况下，鸟嘌呤与胞嘧啶配对，腺嘌呤配对胸腺嘧啶。
7.METHOD It was synthesized from guanine via chlorination, condensation, hydrolysis.

8.The nucleoside guanosine triphosphate (GTP) is derived from guanine, and supplies energy for certain enzymecatlyzed metabolic reactions.
鸟嘌呤三磷核苷酸源于鸟嘌呤，它在代谢反应中为某些酶提供能量。
9.Guanosine (guanine nucleoside) A nucleoside present in DNA and RNA and consisting of guanine linked to D- ribose via a B-glycosidic bond.
（鸟嘌呤核苷）是存在于DNA和RNA中的一种核苷，由鸟嘌呤通过B糖苷键连接D—核糖所组成。
10.Each inpidual chain is composed of four bases, called A (adenine), C (cytosine), G (guanine) and T (thymine), that may occur in any order.
每一条独立的链都由4种碱基，A（腺嘌呤），C（胞嘧啶），G（鸟嘌呤），T（胸腺嘧啶），随即排列而构成。
