- Chloroplasts and mitochondria are prokaryotic.They have their own genes on a small, circular chromosome but no nucleus. This chromosome has little non-coding DNA, similar to those of bacteria. Why do bacteria cells not have chloroplasts?
DNA and RNA Quantitation Gram Staining Nucleus Answer Yes, all bacteria have plasmids. Plasmids are a small, circular,double-stranded DNAmolecule that naturally exist in all bacterial cells. Every bacterial cell has its own plasmid which is separated from chromosomal DNA. These plasmids have the ab...
In which environments do bacteria live?Question:In which environments do bacteria live?Prokaryotes:These are organisms without a distinct nucleus and nuclear membrane or nucleolus. They contain a single chromosome. The nature of DNA is circular, naked, and not complexed with histones. It has no me...
Bacteria have the ability to modify their genetic structure using the transferral of plasmids, a small circular DNA molecule containing genetic information that allows the bacterium to overcome environmental stresses. Plasmids are either picked up by a bacterium from its environment, or passed from ba...
Do archaea have circular chromosomes? While archaea, like many bacteria,possess circular chromosomesit has become apparent that, at the levels of DNA replication machinery and mechanism, mode of genome segregation and even cell division machinery, many archaeal species display more eukaryotic-like proper...
However, numerous affected ferrets have been observed for a longer period of time and have had their cough persist for as long as 4 years (Kiupel et al., 2012). h Abscesses Etiology A variety of bacteria have been associated with abscesses and localized infection of the lung, liver, ...
Why are bacteria classified as prokaryotes? Why don't prokaryotes have introns? What are two distinguishing characteristics of prokaryotes? What is gene regulation in prokaryotes? Do prokaryotes have single-stranded DNA? Where does protein synthesis occur in prokaryotes?
The CRISPR/Cas system which is known to act as a part of adaptive immunity in bacteria and archaea, where spacer sequence of already exposed bacteriophages, facilitate the Cas proteins in recognizing and cleaving the exogenous DNA specifically (Barrangou et al., 2007; Horvath and Barrangou, 2010...
DNA methylation is a mechanism used by eukaryotes to do what? Do bacteria have RNA in their genome like viruses do? What is methylation used for in prokaryotes? In eukaryotes? Explain why eukaryotes have three (3) RNA polymerases while prokaryotes only have one. Do bacteria have RNA or DNA...
What would you need to do to a plasmid vector in order to prepare it to receive the foreign DNA?PlasmidPlasmids are extra-chromosomal circular double stranded DNA having their origin of replication and provide the bacteria with some special phenotype....
