Restriction enzymes are essential tools for recombinant DNA technology that have revolutionized modern biological research; however, they have limited sequence specificity and availability. The ...

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 ...

Plastid DNA was isolated from the chloroplasts of tomato (Lycopersicon esculentum var Traveler 76) leaves and the chromoplasts of ripe tomato fruit. Comparisons of the two DNAs were made by ...

A new method can test the activity of thousands of RNA enzymes, called ribozymes, in a single experiment. The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA ...

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