Genes — discrete segments of long DNA molecules — transcribe their sequences onto single-strand messenger RNA molecules, which then serve as templates for proteins.
对遗传信息进行编码。基因——长长的脱氧核糖核酸分子中的不连续的片段——把它们的序列转录成单线信使核糖核酸分子,核糖核酸又成为蛋白质的模板。
Unlike most genes that are encoded as DNA and produce proteins, these tiny genes act by controlling much larger messenger RNAs, which carry the protein-making instructions of the DNA.
不像大多数编码为DNA和产生蛋白质的基因那样,这些微小基因的作用是通过控制更大的信使RNAs,传递DNA制造蛋白质的指令。
In short, DNA makes messenger RNA, and messenger RNA makes proteins.
简言之,脱氧核糖核酸产生了信使核糖核酸,信使核糖核酸又产生了蛋白质。
It's called cDNA or complimentary DNA to indicate that it's a copy, a complimentary copy of the messenger RNA.
它叫cDNA或者互补DNA,意味着它是一个拷贝,一个信使RNA反转录得出的DNA拷贝
The end result of transcription is not double stranded DNA, it's single stranded RNA where the RNA that's produced is called messenger RNA.
最终的转录产物并非双链的DNA,而是单链的RNA,称为信使RNA
Before, we talked about how do you know what messenger RNA to make, how do you know what RNA to copy from a DNA template?
在之前的课上,我们说到如何判断mRNA的具体序列,如何判断RNA从DNA模板复制了什么
