Cloned DNA (cDNA) libraries are produced from the mRNA present in a cell. Complementary DNA sequences can be made and inserted into new cells. These fragments are typically spliced into a plasmid and inserted into a live cell. Knowing the sequence of the plasmid is very helpful in studying ...
nuclease genes, such as restriction endonuclease I disclose a novel method for direct cloning in E. coli. Also provided are novel strains, which facilitate the application of the method. The method of the present invention, has been successful and been used for cloning of a number of genes ...
In an attempt to identify genes that are involved in Drosophila embryonic cardiac development, we have cloned and characterized a gene whose function is required late in embryogenesis to control heart rate and muscular activity. This gene has been named held out wings (how) because hypomorphic muta...
In Vitro Fertilization Definition: a way for organisms to have babies that are biologically their own. Procedure: Take an egg cell from the mom Take a sperm cell from the dad Combine the sperm and egg in a petri dish and let it combine and grow into an embryo. Put the embryo(s) back...
To date, only two clubroot resistance genes have been cloned, and their resistance has broken down as a result of newly evolved virulent Pb isolates. In this study, the newly identified resistance gene WTS confers resistance ...

Y-linked and X-linked zinc finger genes from humans and mice were recently cloned and characterized. The Y-linked zinc finger gene was originally thought to be the testis-determining factor. However, at the present time, it seems clear that this gene is not the master gene triggering the ...
cloned and used to make viral protein in a test tube. Large quantities of viral protein synthesized from the cloned DNA is then purified and used as the vaccine. Synthesized protein from cloned DNA, or a set of viral proteins used for immunizations, are referred to as recombinant inactivated...
In recent years, significant progress has been made on the biochemistry of gibberellin biosynthesis and on the mechanisms by which gibberellin levels are regulated in plants. There have also been major advances in the understanding of gibberellin signaling, with several key genes being cloned. This ...
