The ability of EIEC to invade and colonize the surface of epithelial cells is influenced by many virulence factors. This study aimed to investigate the distribution of virulence ... WebThe identification of DNA as the genetic material and the elucidation of its structure revealed that genetic information must be specified by the order of the four bases (A, C, G, and T) that make up the DNA molecule. …
WebThe flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma ( Figure 15.3 ), which states that genes specify the sequence of mRNAs, which, in turn, specify the sequence of proteins. The decoding of one molecule to another is performed by specific proteins and RNAs.
