In molecular biology, endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain (namely DNA or RNA).Some, such as deoxyribonuclease I, cut DNA relatively nonspecifically (with regard to sequence), while many, typically called restriction endonucleases or restriction enzymes, cleave only at very specific nucleotide sequences.
BMC Molecular and Cell Biology is a peer-reviewed open-access scientific journal that covers the fields of ... the journal had an impact factor of 2.4 in 2023. [6 ...
Depiction of the restriction enzyme (endonuclease) HindIII cleaving a double-stranded DNA molecule at a valid restriction site (5'–A|AGCTT–3').. In biochemistry, a nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds that link nucleotides together to form nucleic acids.
More than 3,600 restriction endonucleases are known which represent over 250 different specificities. [7] Over 3,000 of these have been studied in detail, and more than 800 of these are available commercially. [8] These enzymes are routinely used for DNA modification in laboratories, and they are a vital tool in molecular cloning. [9] [10] [11]
It was established in October 2000 [1] and covers all aspects of molecular and cell biology. The editor-in-chief is Kim Baumann. [2] According to the Journal Citation Reports, the journal has a 2021 impact factor of 113.915, ranking it 1st out of 194 journals in the category "Cell Biology". [3]
Molecular and Cellular Biology is a biweekly peer-reviewed scientific journal covering all aspects of molecular and cellular biology. It is published by the American Society for Microbiology and the editor-in-chief is Peter Tontonoz (University of California, Los Angeles). It was established in 1981. The h-index (1981-2021) is 338.
According to the Journal Citation Reports, the journal has a 2020 impact factor of 3.885, ranking it 147th out of 297 journals in the category "Biochemistry and Molecular Biology" [1] and 121st out of 195 journals in the category "Cell Biology".
In molecular biology, XhoI is a type II restriction enzymes that recognise the double-stranded DNA sequence CTCGAG and cleaves after C-1. [1] Type II restriction endonucleases are components of prokaryotic DNA restriction-modification mechanisms that protect the organism against invading foreign DNA.
