WebbThe central region of the cell in which prokaryotic DNA resides is called the nucleoid region. In addition, prokaryotes often have abundant plasmids, which are shorter, circular DNA molecules that may only contain one or a few genes. WebbThe region in the cell containing this genetic material is called a nucleoid (Figure 1). Some prokaryotes also have smaller loops of DNA called plasmids that are not essential for normal growth.

WebbOrigin of transcription on prokaryotic organisms Prokaryotes are mostly single-celled organisms that, by definition, lack membrane-bound nuclei and other organelles. The central region of the cell in which prokaryotic DNA resides is called the nucleoid region. WebbProkaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid. They also may contain small rings of double-stranded extra …
WebbThe Sigma subunit is a part of the prokaryotic RNA polymerase enzyme that recognizes and binds to the promoter region of DNA, which is located upstream of the gene to be transcribed. This binding of the Sigma subunit to the promoter region of DNA is an essential step in initiating the transcription process. http://ib.bioninja.com.au/standard-level/topic-3-genetics/32-chromosomes/prokaryotic-genetics.html
