The virus consists of ribonucleic acid ( rna ) , surrounded by a nucleocapsid ( red ) and a lipid envelope ( green ) .
该病毒由围绕在核蛋白(红色)周围的核糖核酸(rna)以及脂质表面(绿色)组成。
For instance , a kind of rna called a ribozyme can cut up viral dna and trigger cell suicide to ensure the infection does not spread .
比如,一种称作核酶的核糖核酸(rna)可以切断病毒的dna,引发细胞自杀,从而确保感染不会扩散。
Using synthetic messenger rna ( mrna ) instead of proteins purified from viruses , german scientists have shown they can protect mice , ferrets , and pigs against influenza .
Twenty-eight percent might seem like a low number , the researchers say , but it 's significant given that rna can degrade over time , so fresher samples would likely be more accurate .
That information determined whether or not a string of rna was snipped .
这一信息决定某段核糖核酸(rna)是否被剪断。
But upon closer examination , the researchers also detected pieces of rna .
但是经过仔细的检测,研究人员还检测出核糖核酸(rna)片段。
Rathore used a new technique , called rna interference , to construct a genetic sequence that blocked the gossypol-producing enzyme in the seeds only .
Scientists thought that most rna in a cell was messenger rna generated by protein-coding genes , rna in ribosomes , or a sprinkling of other rna elsewhere .
