DNA Molecules

Some articles on dna molecules, dna, molecule:

History of Molecular Cloning
... restriction endonucleases, enzymes that could cleave DNA molecules only when specific DNA sequences were encountered ... restriction enzymes cleaved chromosome-length DNA molecules at specific locations, and that specific sections of the larger molecule could be purified by size fractionation ... Using a second enzyme, DNA ligase, fragments generated by restriction enzymes could be joined in new combinations, termed recombinant DNA ...
Restriction Digest
... A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing ... It is sometimes termed DNA fragmentation (this term is used for other procedures as well) ... enzymatic technique can be used for cleaving DNA molecules at specific sites, ensuring that all DNA fragments that contain a particular sequence have the same size ...
Fragmentation (cell Biology) - DNA Cloning
... DNA cloning can be performed spontaneously by the cell for reproductive purposes ... DNA cloning can also be performed intentionally by laboratory researchers ... Here, DNA fragmentation is a molecular genetic technique that permits researchers to use recombinant DNA technology to prepare large numbers of ...

Famous quotes containing the word dna:

    Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.
