WebcDNA libraries have been broadly used to determine the expressed portion of protein-coding genes in eukaryotes. The construction of a cDNA library involves the extraction and purification of mRNA (Fig. 2.8). These mRNAs are used as a template for the synthesis of cDNA by the process of reverse transcription in the presence of oligo dT primer. cDNA is created from a mature mRNA from a eukaryotic cell with the use of reverse transcriptase. In eukaryotes, a poly-(A) tail (consisting of a long sequence of adenine nucleotides) distinguishes mRNA from tRNA and rRNA and can therefore be used as a primer site for reverse transcription. This has the problem … Meer weergeven A cDNA library is a combination of cloned cDNA (complementary DNA) fragments inserted into a collection of host cells, which constitute some portion of the transcriptome of the organism and are stored as a " Meer weergeven • Functional cloning Meer weergeven • Functional Annotation of the Mouse database (FANTOM) • examples of cDNA synthesis and cloning Meer weergeven cDNA libraries are commonly used when reproducing eukaryotic genomes, as the amount of information is reduced to remove the … Meer weergeven cDNA molecules can be cloned by using restriction site linkers.

WebMaking a cDNA Library From mRNA. First, eukaryotic cells are lysed and the mRNA is purified. Next, reverse transcriptase plus primers containing oligo(dT) stretches are added. The oligo(dT) hybridizes to the adenine in the mRNA polyA tail and acts as a primer for reverse transcriptase, which synthesizes a DNA strand complementary to the mRNA.
