Solved Discuss how bacterial and archaeal DNA is organized

WebBacterial and archaeal DNA is organized differently from eukaryotic DNA. While eukaryotic DNA is contained in a nucleus, bacterial and archaeal DNA is contained in the cytoplasm, where it is organized into a single, circular chromosome. This chromosome is not associated with histone proteins, as in eukaryotes, and does not have introns or exons. WebIn many bacteria, flagella and evolutionarily conserved type IV pili are required for the formation of biofilms on solid surfaces or floating at the air-liquid interface of liquid media. Similarly, in many archaea it has been demonstrated that type IV pili and, in a subset of these species, archaella are required for biofilm formation on solid surfaces. porsche 924 air suspensionWebMicrobial community compositions were characterized using bacterial and archaeal hypervariable V3–V4 regions of 16S rRNA gene sequencing.
