| 1. | Chromatin is the material that makes up chromosomes ; it consists of dna complexed with proteins
由dna和蛋白质组成的染色质，是构成染色体的原料。 |
| 2. | Ribosomes - - particles composed of rna and proteins that are the sites of protein synthesis
粒线体- -由核糖核酸和蛋白质组成的颗粒,是蛋白质合成的场所 |
| 3. | Such a huge amount of types is due to the different sequences of amino acids which compose the proteins in the peptide chains
造成种类如此众多的原因主要是20种参与蛋白质组成的氨基酸在肽链中的排列顺序不同所引起的。 |
| 4. | A human hair co ists mainly of a protein called keratin . it also contai some moisture and the trace metals and minerals found in the rest of the body
人类的头发主要由一种叫角朊的蛋白质组成，并含有水分及在身体其他部分也可找到的微量金属和矿物质。 |
| 5. | A human hair consists mainly of a protein called keratin . it also contains some moisture and the trace metals and minerals found in the rest of the body
人类的头发主要由一种叫角朊的蛋白质组成，并含有水分及在身体其他部分也可找到的微量金属和矿物质。 |
| 6. | L - arginine is a conditionally essential basic amino acid ， the building blocks of protein ； primarily involved in urea metabolism and excretion as well as dna synthesis
精氨酸是一种基础氨基酸，是蛋白质组成的基石，它从根本上解决尿素的新陈代谢和排泄。 |
| 7. | All about your hair a human hair consists mainly of a protein called keratin . it also contains some moisture and the trace metals and minerals found in the rest of the body
人类的头发主要由一种叫角朊的蛋白质组成，并含有水分及在身体其他部分也可找到的微量金属和矿物质。 |
| 8. | It was found that prion which is made up of proteins exclusively is the main cause and it has two forms , i . e , normal form prpc and abnormal one prpsc
目前已知疯牛病的致病因子是完全由蛋白质组成的朊病毒( prion ) ，它存在“正常”和“致病”两种状态，分别被称为prp ~ c和prp ~ sc 。 |
| 9. | Two protein peaks can be obtained by bio - gel p - 6 chromatography and both peaks have antimicrobial activity . so the bacteriocin is consisted of two proteins with different mw . only one protein with larger mw can be detected through tricine - sds - page , and its mw is about 8 , 570da
采用30硫酸铵就能完全把发酵液中的细菌素全部沉淀，通过生物胶bio - gelp - 6层析发现细菌素被分离出两条抗菌蛋白峰，这表明r21 - 4产生的细菌素是由两种不同分子量的蛋白质组成的，通过tricine - sds - page检测，只能检测到一条分子量相对较大的细菌素，分子量在8 , 570da左右。 |
| 10. | Telomerase is a ribonucleoprotein complex ( rnp ) composed by its rna component and protein subunits . telomerase can synthesize telomeric dna onto chromosomal ends using its own rna component as a template , elongate the length of telomere , increase cell life and even induce cell immortalization
端粒酶( telomerase )是由端粒酶rna和蛋白质组成的一种核糖核蛋白复合物( rnp ) 。端粒酶含有引物特异识别位点，能以自身rna为模板，逆转录合成端粒dna并加到染色体末端，使端粒延长，从而延长细胞的寿命甚至使其永生化。 |
