What else can I help you with?
CDNA is significant when?
cDNA is significant because it is a synthesized DNA copy of mRNA that lacks introns and contains only exons. This allows for the study of gene expression and regulation, as well as the production of recombinant proteins or gene therapy vectors. cDNA is particularly useful in understanding genetic diseases and developing new therapeutics.
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.
In genetics what does complementary DNA mean?
Complementary DNA (cDNA) is DNA that has been copied from an mRNA through a reverse transcriptase enzyme. cDNA contains a copy of the original DNA sequence that made the mRNA - but without the introns (as these are cut out to create mRNA).
Which of these statements does not describe introns?
Non-expressed
What is the purpose of the cDNA synthesis?
The purpose of cDNA synthesis is to synthesize a copy of DNA from mRNA. This means that it is involved in the duplication of DNA that occurs when a cell divides. As a result, without cDNA synthesis, life would not exist as cells would not be able to divide.
Does a cDNA library have only exons?
Yes, a cDNA library contains only exons because it is generated from mRNA, which has had introns removed through the process of splicing. cDNA represents the expressed regions of the genome and does not contain non-coding introns found in genomic DNA.
What does c in CDna stand for?
The "c" in cDNA stands for complementary. cDNA is synthesized from mRNA using reverse transcriptase, resulting in a complementary DNA strand that lacks introns and represents the protein-coding regions of a gene.

Can clones isolated from cDNA libraries contain promoter sequences?
No, clones isolated from cDNA libraries do not contain promoter sequences because the cDNA synthesis process does not retain regulatory elements such as promoters. cDNA is made from mature mRNA and lacks the non-coding regions found in genomic DNA, including promoters. Therefore, clones isolated from cDNA libraries do not include promoter sequences.
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.

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.

Is cDNA complementary to mRNA?
Yes, cDNA is complementary to mRNA.
What is the full form of cdna?
CDNA = Complimentary Deoxyribose Nucleic Acid
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.
In genetics what does complementary DNA mean?
Complementary DNA (cDNA) is DNA that has been copied from an mRNA through a reverse transcriptase enzyme. cDNA contains a copy of the original DNA sequence that made the mRNA - but without the introns (as these are cut out to create mRNA).
How can I create cDNA in the laboratory?
To create cDNA in the laboratory, you can follow these steps: Extract RNA from the cells or tissue of interest. Use reverse transcriptase enzyme to convert RNA into cDNA. Purify and amplify the cDNA using PCR (polymerase chain reaction). Verify the cDNA sequence through sequencing techniques.
