E. coli is commonly used to host various cloning vectors, such as plasmids, cosmids, F factors, and bacterial artificiak chromosomes (BACs). that includes the cisplugin-autotooltip__default plugin-autotooltip_bigCis and trans: In genetics, cis and trans are terms used to describe the relative physical locations of genes or genetic elements. If two genes are in cis, this means that they are physically located on the same DNA molecule. If two genes are in trans, this means that they are physically located on two different-acting elements of a promoterplugin-autotooltip__default plugin-autotooltip_bigPromoter: has multiple closely related but subtly different meanings depending on context:
* In bacteria, a promoter is a cis-acting DNA sequence near the transcription start site of a gene or operon that binds to bacterial RNA polymerase. * In eukaryotes, the formal definition of a promoter (also called a basal promoter) is a RNA and an intiator, and the proteinplugin-autotooltip__default plugin-autotooltip_bigProtein: a molecule that is formed by the translation of messenger RNAs (mRNAs). Functions that proteins provide are what usually give organisms their phenotypes. coding genesplugin-autotooltip__default plugin-autotooltip_bigGene: read Chapters 02, 03, 04, 05, and 06 for a definition of gene :-) $malP$ and $malQ$.
