Learn more about the DNA transcription process, where DNA is converted to RNA, a more portable set of instructions for the cell. The process of transcription can be visualized by electron ...
Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...
This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding of DNA and RNA structure. Cytosine can be synthesized chemically or isolated from ...
RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...
在细胞中，染色体中含有的DNA可作为制造细胞所需物质的永久性百科全书。但要真正完成生物进程，细胞需要从染色体转录RNA。 RNA最重要的功能之一，就是在细胞里“复印”DNA片段，细胞内的 ...
