| 1. | The sugar in all the nucleotides of dna is deoxyribose . 所有DNA的核苷酸中的糖均是脱氧核糖。 |
| 2. | Ribose and deoxyribose are constituents of the nucleic acids rna and dna . 核糖与脱氧核糖分别是核糖核酸与脱氧核酸(DNA)的结构成分。 |
| 3. | Two major kinds of nucleic acids are found in living things: deoxyribonucleic acid or dna and ribonucleic acid or rna . 生物中存在着两大类核酸:脱氧核糖酸和核糖核酸。 |
| 4. | The sugar in all the nucleotides of dna is deoxyribose 所有dna的核苷酸中的糖均是脱氧核糖。 |
| 5. | Ribose and deoxyribose are constituents of the nucleic acids rna and dna 核糖与脱氧核糖分别是核糖核酸与脱氧核酸( dna )的结构成分。 |
| 6. | Deoxyribose a pentose ( five - carbon ) sugar that is a component of the nucleotides that make up dna 脱氧核糖:组成dna核苷的一种戊糖(五个碳) 。 |
| 7. | Deoxy sugar a sugar in which oxygen has been lost by replacement of a hydroxyl group ( oh ) with hydrogen ( h ) . the most important example is deoxyribose 脱氧糖:羟基被氢原子置换导致失去氧的一类单糖。最重要的脱氧糖就是脱氧核糖。 |
| 8. | Rna was once seen as the working arm of dna , which carries the genetic code , but studies show it can " silence " genes and even help cut them up 曾经认为rna是脱氧核糖酸的工作臂,其携带遗传密码,但现在研究表明,它能使基因“沉默” ,甚至帮助去掉某些基因。 |
