    Bacteria and Archaea The Archaea are presently recognized as one of the two main domains of prokaryotes. The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several

    called gram stain is used in the identification of bacteria. Bacteria can be gram-positive‚ gram-negative‚ or gram-variable. Most bacteria however‚ are usually gram-positive or gram-negative. Gram-positive and gram-negative bacteria react differently to staining because of the differences in their cell walls. Bacterial cell walls contain a polymer called peptidoglycan. Gram-positive bacteria have more of this polymer than gram-negative bacteria. They are also less complex than gram-negative cell
