a piece of DNA lacking internal, non-coding segments (introns) and regulatory sequences that determine transcription
a single-stranded DNA complementary to an RNA, synthesized from it by reverse transcription in vitro
DNA molecule usually obtained by a reverse transcription of an mRNA molecule.
Copy DNA, prepared from mRNA using an enzyme called reverse transcriptase. The cDNA can then be used as a probe to locate the real gene by hybridisation.
DNA that is synthesized from a messenger RNA template; the single-stranded form is often used as a probe in physical mapping.
A single–stranded DNA complementary to an RNA from which it was synthesized using reverse transcriptase.
A segment of DNA identical in base sequence to at least part of the coding sequence of a gene, generated in the laboratory from a natural mRNA molecule. cDNA can be produced in large quantities for sequencing and other genetic studies.
Single or double stranded DNA made from RNA template using the enzyme reverse transcriptase.
DNA prepared by "reverse transcription" of RNA; that is, the RNA is used as a template for the synthesis of a complementary DNA molecule.
complementary DNA - DNA that is synthesized from a messenger RNA template. Viral reverse transcriptase can be used to synthesize DNA that is complementary to RNA (for example an isolated mRNA).
Complementary DNA. DNA copies of the mRNA expressed in a specified tissue. cDNA sequencing has the advantage of only representing expressed genes. Since only ~3% of the vast quantity of DNA in the human genome are coding sequences, cDNA sequencing is particularly useful in certain situations. See EST.
Complementary DNA; DNA which is synthesised from a messenger RNA template which is complementary to the coding strand of genomic DNA.
See complementary DNA (cDNA)
a single-stranded DNA complementary to, and synthesized from, a specific mRNA.
Complementary DNA. The product of reverse transcription of RNA.
DNA, See complementary DNA.
A DNA strand copied from mRNA using reverse transcriptase. A cDNA library represents all of the expressed DNA in a cell.
abbreviation for "complementary DNA," which matches a given RNA that serves as a template for synthesis of the DNA in the presence of reverse transcriptase.
DNA copies synthesized from a messenger RNA template using the enzyme reverse transcriptase; the single-stranded copy is often used as a probe to identify complementary sequences in DNA fragments or genes of interest.
Complementary DNA, enzymatically synthesized using an RNA molecule as template. and contains DNA nucleotides.
Complementary DNA, resulting from the "transcription" of mRNA by means of a specific enzyme called reverse transcriptase. Thus, the cDNA represents the genetic information that is actually converted into proteins.
DNA which has been synthesised using an RNA template (cDNA = copy or complementary DNA). Most frequently used to describe double-stranded DNA copies of mRNA sequences eg. cDNA libraries. May be single or double stranded.
(copy DNA) DNA synthesised from an RNA template using the enzyme reverse transcriptase.
Complementary DNA produced from a RNA template by the action of RNA-dependent DNA polymerase.
(copy DNA) DNA strand copied from mRNA using reverse transcriptase.
A DNA molecule synthesized from an mRNA molecule. They can be used experimentally to determine the sequence of an mRNA.
DNA produced in vitro in such a way that the sequence of bases is complementary to a particular messenger RNA. Complementary DNA (cDNA) is used to study gene expression because it is more stable than RNA and is more amenable to recombinant cloning techniques.
A DNA strand copied in vitro from mRNA using reverse transcriptase. It is complementary to the RNA from which it was reverse transcribed.
complementary DNA. DNA synthesized by RNA-directed DNA polymerase as a copy of RNA, usually isolated mRNA or viral genomic RNA. It differs in sequence from eukaryotic chromosomal DNA by the absence of introns.
DNA that is synthesized to be complementary to a mRNA molecule. By definition a cDNA represents a portion of the DNA that specifies a protein (is translated). If the sequence of the cDNA is known, by complementarity, the sequence of the DNA is known.
Complementary DNA. cDNA is a single stranded piece of DNA that is complementary to a piece of RNA.
An artificial piece of DNA that is synthesized from an mRNA (messenger RNA) template and is created using reverse transcriptase. The single stranded form of cDNA is frequently used as a probe in the preparation of a physical map of a genome. cDNA is preferred for sequence analysis because the introns found in DNA are removed in translation from DNA ---- mRNA ---- cDNA.
the DNA of the chromosome i.e. chromosomal DNA.
single strand sequence of DNA. Generated in vitro by copying a strand of RNA using a polymerase enzyme. A sequence of cDNA is also called a "transcript".
(Complementary DNA ) — DNA synthesized from a messenger RNA rather than from a DNA template. This type of DNA is used for cloning as it encodes a copy of a gene that is readily usable.
