Lambda phage
Enterobacteria phage λ (lambda phage) is a temperate phage that lives in E. coli. Once the phage is inside its host, it may integrate itself into the host's DNA.

Lambda
A temperate phage that infects E. coli. Derivatives of phage lambda are widely used as cloning vectors.

lambda Any type of cloning vector (cosmids) containing cos sites necessary for propagation in bacteriophage lambda. Cosmid clones can be used to clone DNA fragments of up to 15 kb.
library A collection of clones in any type of vector.

Lambda."The point of meeting of the lambdoidal and sagittal sutures; it is in the middle line about 6.5 cm. above the inion.

Lambda: see Bacteriophage Lambda.

Leucine zipper: A motif found in certain proteins in which Leu residues are evenly spaced through an a-helical region, such that they would end up on the same face of the helix.

Lambdoidal lambda = like the Greek letter lambda.
lamella One of the two plates forming a gill in a bivalve mollusc. One of the thin layers of bone laid concentrically around an osteon (Haversian canal). Any thin, platelike structure.

[lambda] [phiX-174] [T2] [T4] Bacteroidetes Balanced polymorphism Barbiturate Barcoding Barr body BaseMolecule or ion that can take a proton from an acid.

Cosmids -- plasmid vectors designed for cloning large fragments of eukaryotic DNA; the vector is a plasmid into which phage lambda cohesive end sites have been inserted. CpG islands -- areas of multiple CG repeats in DNA.

Lambda bacteriophage is the basis of many E. coli vectors which are used for cDNA and genomic DNA libraries.

Participants used restriction enzymes to cut DNA from the bacteriophage lambda and analyzed the resulting DNA fragments by agarose gel electrophoresis.

Artificially constructed cloning vector containing the cos gene of phage lambda.

If an entire molecule of DNA from the virus "bacteriophage lambda" were shown at this scale, the image would be 970 meters high. For the bacterium Escherichia coli, the image would be 80 kilometers long.

Cosmid A type of cloning vector which is based on a plasmid but which contains one copy (or sometimes two copies) of the lambda cohesive end.

A crossover event, such as the integration of phage lambda, that requires homology of only a very short region and uses an enzyme specific for that recombination.

COSMID - A genetically-engineered plasmid containing bacteriophage lambda packaging signals and potentially very large pieces of inserted foreign DNA (up to 50 kb) which can be replicated in bacterial cells.

Lambda kills bacteria instantly, he reasoned; I'll try the experiment over with something that will slowly kill the bacteria to see if, given a chance, bacteria can direct their mutations.

An E. Coli virus. Commonly used bacteriophases in biology labs are T4, M13 and lambda phages.
