DNA Replication, Transcription, and TranslationPOPO
In this lesson, you'll learn about the roles of DNA, mRNA, tRNA, and ribosomes in protein formation. We'll provide an overview of the processes of transcription and translation in protein formation. The Journey from Gene to Protein It's commonly known that DNA is 'the building block of...
答:原核细胞转录和翻译是耦联的,称为耦联性转录与翻译。 这是因为原核细胞没有细胞核,转录和翻译没有空间阻隔,是同时进行的。不同于真核细 胞,真核细胞转录在细胞核完成,转录出的mRNA经过加工后,释放出细胞质,在细胞质进 行翻译。而原核细胞没有细胞核,其DNA也没有内含子,在核区转录出mRNA不需要加工就 可...
form an RNA strand by using one of the DNA strands as a template. This is done through complementary base pairing, however in the RNA chain, the base thymine is replaced by uracil.RNA polymeraseis the enzyme involved in the formation of the RNA strand and the uncoiling of the double ...
A cell builds its proteins from the instructions encoded in its genome. The genome contains all the genetic information necessary for the cell to function and develop. It consists of DNA, which contains the instructions for building proteins through the process of transcription and translation. The...

Transcription by RNA polymerase (RNAP) is coupled with translation in bacteria. Here, we observe the dynamics of transcription and subcellular localization of a specific gene locus (encoding a non-membrane protein) in living E. coli cells at subdiffracti
