DNA replication is suggested by the restriction alleviation phenomena: the phenotypic decrease of restriction activity on invading DNA, it is induced by several DNA damaging agents or is constitutively seen in some mutants. The underlying mechanism varies among the enzyme subtypes. For EcoKI (Type I ...

... Substitutions are the most common form of mutation. They involve the replacement of one base by another. One codon may be altered so that it now codes for one different amino acid in the protein sequence. The most detrimental substitution mutations seem to be when the 1st or 2nd base of a codon is a ...

Extrachromosomal DNA



Extrachromosomal DNA is any DNA that is found outside of the nucleus of a cell. It is also referred to as extranuclear DNA or cytoplasmic DNA. Most DNA in an individual genome is found in chromosomes but DNA found outside of the nucleus also serves important biological functions.In prokaryotes, nonviral extrachromosomal DNA is primarily found in plasmids whereas in eukaryotes extrachromosomal DNA is primarily found in organelles. Mitochondrial DNA is a main source of this extrachromosomal DNA in eukaryotes. Extrachromosomal DNA is often used in research of replication because it is easy to identify and isolate.Extrachromosomal DNA was found to be structurally different from nuclear DNA. Cytoplasmic DNA is less methylated than DNA found within the nucleus. It was also confirmed that the sequences of cytoplasmic DNA was different from nuclear DNA in the same organism, showing that cytoplasmic DNAs are not simply fragments of nuclear DNA.In addition to DNA found outside of the nucleus in cells, infection of viral genomes also provides an example of extrachromosomal DNA.
