Enterobacteria phage λ (lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E. coli). It was discovered by Esther Lederberg in 1950. [ 2 ]
The simplest DNA end of a double stranded molecule is called a blunt end. Blunt ends are also known as non-cohesive ends. In a blunt-ended molecule, both strands terminate in a base pair. Blunt ends are not always desired in biotechnology since when using a DNA ligase to join two molecules into one, the yield is significantly lower with blunt ...
EcoRI (pronounced "eco R one") is a restriction endonuclease enzyme isolated from species E. coli. It is a restriction enzyme that cleaves DNA double helices into fragments at specific sites, and is also a part of the restriction modification system. [1]
HU and integration host factor function as auxiliary proteins in cleavage of phage lambda cohesive ends by terminase is an academic journal written by the Department of Molecular Genetics. In their article, they created isogenic strains of E.coli that were lacking HU or integration host factors to test whether bacteriophage would grow under ...
The invention of the Lambert cylindrical equal-area projection is attributed to the Swiss mathematician Johann Heinrich Lambert in 1772. [1] Variations of it appeared over the years by inventors who stretched the height of the Lambert and compressed the width commensurately in various ratios.
Trump’s plan to eliminate taxes on Social Security benefits would help current beneficiaries, but future recipients may be hurt by the move.
Recognition sequences in DNA differ for each restriction enzyme, producing differences in the length, sequence and strand orientation (5' end or 3' end) of a sticky-end "overhang" of an enzyme restriction. [31] Different restriction enzymes that recognize the same sequence are known as neoschizomers. These often cleave in different locales of ...
The birth rate in America has long been on a decline, with the fertility rate reaching historic lows in 2023. More women between ages 25 to 44 aren’t having children, for a number of reasons.
