Science / Genetics / Cosmid: Artificially constructed cloning vector containing the cos gene of phage lambda. Cosmids can be packaged in lambda phage particles for infection into e. Coli: this permits cloning of larger dna fragments (up to 45 kb) than can be introduced into bacterial hosts in plasmid vectors.

Cloning Vector

Science / Genetics / Cloning Vector: Dna molecule originating from a virus, a plasmid, or the cell of a higher organism into which another dna fragment of appropriate size can be integrated without loss of the vectors capacity for self- MORE

Arrayed Library

Science / Genetics / Arrayed Library: Individual primary recombinant clones (hosted in phage, cosmid, yac, or other vector) that are placed in two-dimensional arrays in microtiter dishes. Each primary clone can be identified by the identi MORE

Yeast Artificial Chromosome (YAC)

Science / Genetics / Yeast Artificial Chromosome (YAC): A vector used to clone dna fragments (up to 400 kb): it is constructed from the telomeric, centromeric, and replication origin sequences needed for replication in yeast cells. Compare cloning vector, MORE
