WebJan 24, 2024 · Archaea are single-celled organisms that are similar to bacteria, though they have different characteristics. They can be spherical, rod-shaped, spiral, or rectangular. … WebMost prokaryotes reproduce rapidly. Due to their fast growth and simple genetics, E. coli bacteria are widely used in molecular biology. In the laboratory, a gene can be transferred into E. coli bacteria on a small, circular DNA molecule called a plasmid. The plasmid is taken up by the bacteria in a process called transformation.

WebIn E. coli, RNA polymerase comprises six polypeptide subunits, five of which compose the polymerase core enzyme responsible for adding RNA nucleotides to a growing strand. The sixth subunit is known as sigma (σ). The σ factor enables RNA polymerase to bind to a specific promoter, thus allowing for the transcription of various genes. WebDec 13, 2012 · Firstly, the free double-stranded DNA ends must have some kind of protection so that intracellular nucleases do not degrade them . Secondly, the telomeres, which are the ends of the linear DNA molecules, will require a different process for DNA replication . For protection, there are two types of telomeres that have been observed.
