c-DNA library is a combination of cloned c-DNA(complementary DNA)fragments inserted into a collection of host cells which together constitute some portion of transcriptome(it is a set of all RNA molecules including m-RNA,r-RNA,t-RNA and other non-coding RNA produced in one or a population of cells) of an organism.c-DNA is produced from fully transcribed m-RNA found in the nucleus and therefore contains only the expressed genes of an organism.

What is virtual cDNA library?
I imagine its just an online cDNA library. A cDNA library is of course a collection of cDNA copy sequences. cDNA is where you have mRNA and you use reverse transcriptase to turn a strand of RNA into a DNA equivalent, then use RNAase H to degrade the remaining RNA strand and then use DNA polymerase to create a complete double stranded DNA sequence that is the equivalent of the mRNA. This way you can get the gene without the introns that normal DNA would have.
What is the use of DNA library?
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.
How is cdNA created?
cDNA or complimentary DNA is created by a catalyzed reaction from DNA polymerase and reverse transcriptase which results in the use of mRNA or messenger RNA as template for DNA synthesis.
How do you make a complementary RNA?
cDNA of the gene/mRNA for which you want to make complementary RNA is cloned into special plasmid vectors that have promoters at either ends of the multiple cloning sites (MCS). Using RNA polymerase and nucleotides you can now synthesize RNA complementary to the original mRNA. This is called complementary RNA (cRNA).
What is an antigenome?
An antigenome is a complementary strand of RNA from which the genome of a virus is constructed.

The function of cdna?
hi In vitro we must converted the RNA to cDNA to diagnosis viral RNA in PCR. In vivo RNa viral infected the cell RNA converted to cDNA IN SIDE THE CELL BY REVERSE TRANSCRIPTASE therfore cDNA insertion in the DNA of cell infected thank you hi In vitro we must converted the RNA to cDNA to diagnosis viral RNA in PCR.

What is the advantage of using cDNA library in molecular genetics?
The main advantage of cDNA library is that it contains only the coding region of a genome.
Does a cDNA library have only exons?
A cDNA library consists only of genes that are expressed, hence they do contain only exons. They contain no introns.
What is a cDNA library used for?
A cDNA library is used for complementary DNA. These DNA are collected as host cells, which can be found in the nucleus. Currently, cDNA libraries are lacking in the enhancer, intron, and several other categories.
What does c in CDna stand for?
There is no letter C in DNA or RNA .
Difference between genomic library and cdna library?
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.

Why you chose mRNA rather than genomic DNA for making a DNA library?
Complementary DNA (cDNA) is a doublestranded DNA version of RNA . Messenger RNA is a more useful predictor of a polypeptide sequence than DNA, because the introns have been spliced out. Scientists use cDNA rather than mRNA itself because RNAs are less stable than DNA.
How do you make a complementary RNA?
cDNA of the gene/mRNA for which you want to make complementary RNA is cloned into special plasmid vectors that have promoters at either ends of the multiple cloning sites (MCS). Using RNA polymerase and nucleotides you can now synthesize RNA complementary to the original mRNA. This is called complementary RNA (cRNA).
What are the basic steps during obtaining a target gene from the cDNA library?
The advantage of cDNA library is that it contains only the coding region of a genome. To prepare a cDNA library, the first step is to isolate the total mRNA from the cell type of interest.Then the enzyme reverse transcriptase is used to synthesize a DNA strand complementary to each mRNA molecule. After the single-stranded DNA molecules are converted into double-stranded DNA molecules by DNA polymerase, they are inserted into vectors and cloned.
