Both , like the genes for ribosomal rna , are old and ubiquitous .
这两种基因就像核糖体rna基因一样,来源已久,而且普遍存在。
Dr szyf and his team looked at a gene that codes for ribosomal rna , which helps control the manufacture of proteins .
斯兹夫博士和他的团队研究了一段核糖体rna编码基因,这个基因参与了蛋白质合成的控制。
They not only identified and sequenced all available ribosomal rna genes in the samples but also deciphered more than 3 million other genes from the bacteria in the people 's guts .
