Members of this viral family tend to have between 29 , 000 and 31 , 000 nucleotides . identifying the genetic sequence of a new virus is important to efforts to treat or prevent it , said dr . julie gerberding , cdc director 。新排出的序列中有29727个核苷酸,完全在冠状病毒中核糖核酸通常的数目范围内。该病毒族中的病毒通常有29000到31000个核苷酸。
The viruses that cause these diseases belong to the picornaviridae family . 1 , 2 both diseases produce painful blisters in the mouth and on the feet , but in other respects they are not related and should not be confused with one another 引起此病的病毒属小核糖核酸病毒属,两种病都是在口腔内和脚上产生疼痛性水疱,但另一方面它们并不相关,不要相互混淆。
Angiogenin belongs to a protein superfamily of rnase . it is the only member being able to stimulate angiogenesis . on the other hand , angiogenin is also the only angiogenic factor known to exhibit ribonucleolytic activity 血管生成素是核糖核酸酶超家族中唯一一个具有促血管生成能力的成员,也是目前已知的所有血管生成因子中独具核糖核酸酶活性的因子。
On the other hand , the raw data of dna , rna sequences and ammo acid sequences of protein have being increasing in recent decades , and computers become indispensible tools in processing so much a lot of data 近十几年,全世界生物学家收集的dna 、 rna (核糖核酸) 、蛋白质氨基酸序列原始数据不断激增,靠人工来处理这样大量的数据显然力不从心,利用计算机处理这些数据成为必然。
Before life as we know it could exist on earth , conditions had to favour the creation of self - replicating molecules that enabled information to be passed on between generations . the first were probably chain - like molecules of amino acids or rna 我们知道,要生物可以在地球存在,地球首先要具备有利条件,让能自我复制的分子产生,使生命资讯可代代相传,而最先产生的很可能是氨基酸或核糖核酸的链状分子。
