Genomic library
A genomic library is produced through the meticulous accumulation of genetic information that lends to different classifications and structures to the level of taxonomy.
The most compelling evidence, as well as the greatest amount of observational data to support the evolutionary model and aid in its refinement, comes from genetics and comparative genomics. The genomic record (the complete library of all sequenced genomes and the genes they contain) is by far the most complete record of evolution that we have at our disposal. Additionally, the fossil record can be used to test and verify hypotheses regarding timing of emergence, behaviours and morphology of ancestral forms.
a library according to batman and robin!
A cDNA library consists only of genes that are expressed, hence they do contain only exons. They contain no introns.
it is called genomic library
Genomic library
genomic library, a set clones that collectively contain all of the DNA in an organis's genome

Clay tablets were contained in the library. Actually, over 25,000 tablets were contained in the library. Then, Nebuchadrezzar II destroyed it...
cDNA is the short form complementary DNA. cDNA libraries are a combination of cloned cDNA fragments. cDNA libraries are used to express eukaryotic genes in prokaryotes.
lirrary it is the work as a one type of referances for our purposes
A cDNA (complementary DNA) library is a DNA library that has been created from mRNAs that are present in the cell. Since a cDNA is created from mRNA transcripts, that means that in Eukaryotic organisms there will be no introns or transcriptional factors present in the cDNA library, only exons. Only protein coding regions will be present in a cDNA library. This also means that a cDNA library is often times tissue specific. Since the expression of mRNAs will be different in different tissues of the organism it will appear different then a genomic library. Often times to offset this problem a cDNA library will be composed of different tissues (brain, liver, heart) to encompass a greater variety of the proteins that are expressed. A genomic library will contain all the exons, introns, and transcriptional factors that are not found in the cDNA library. **2/24/2011** cDNA library does contain exons, which is the protein coding regions.
probability of including any DNA sequence in a random libray of N independent recombinants: N= [ln(1-P)] / [ln(1-1/n)] where n= genome size /average insert size in theory, a genomic library should contain all the different sequences, but in practice, a genomic libray is never perfect.
