Expressedplugin-autotooltip__default plugin-autotooltip_bigExpression: a term used to describe the idea that the function of a gene is apparent and can be observed. Genes may not always be expressed all the time in all places. sequenceplugin-autotooltip__default plugin-autotooltip_bigSequence: the precise order of monomers in a polymer. In DNA, it refers to the order of G, A, T, and C nucleotides. In RNA, it refers to the order of G, A, U, and C nucleotides. In proteins, it refers to the order of amino acids. tag: a cDNAplugin-autotooltip__default plugin-autotooltip_bigComplementary DNA (cDNA): DNA that has been reverse transcribed from spliced mRNA using reverse transcriptase. cDNA sequences are useful because they lack intron sequences and therefore contain information about the ORF of intron-containing eukaryotic genes. from a cDNA libraryplugin-autotooltip__default plugin-autotooltip_bigcDNA library: a library that is created from an mRNA sample, usually from a specific tissue source and/or cell type. The mRNAs, representing all the different genes that are expressed in that tissue, are reverse transcribed into cDNAs, which are then cloned and archived for research. that has been sequenced and catalogued.
