Scientists first observed the biological phenomenon of restriction and modification in the 1950s, but they did not identify and isolate restriction enzymes until the late 1960s. 3 In 1970, Hamilton ...

Complementary DNA (cDNA) libraries are standard tools for gene expression studies. In theory, the library contains full-length DNA copies of every mRNA in the starting sample, in abundances ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

Cold Spring Harbor, NY-- Cold Spring Harbor Laboratory Press (CSHLP) announced the release of Restriction Enzymes: A History, available on its website in hardcover format. Restriction enzymes cleave ...

Homologous recombination is an ancient process that functions to conserve genetic integrity and create genetic diversity. It relies on the formation of Holliday junctions — four-stranded DNA ...

Research by Professor of Chemical and Biomolecular Engineering Huimin Zhao and graduate student Behnam Enghiad at the University of Illinois is pioneering a new method of genetic engineering for basic ...

Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...
