cdna
cdna — noun
1. a type of DNA that scientists create in a laboratory by copying a molecule of RN
a type of DNA that scientists create in a laboratory by copying a molecule of RNA, using an enzyme called reverse transcriptase; it is used in genetic research to study genes and how they are expressed in different cells or conditions.
Researchers used cDNA to study which genes were active in the cancer cells.
used to study gene activity (research context)
The scientist made cDNA from messenger RNA using reverse transcriptase in the lab.
synthesised from mRNA using reverse transcriptase
A cDNA library contains copies of all RNA found in a given cell type.
By comparing cDNA from healthy and diseased tissue, doctors can spot genetic differences.
- complementary DNA
the full form of the acronym, used when first introducing the term in formal writing
- copy DNA
a less common alternative name that reflects its origin as a copied molecule
- genomic DNA
DNA extracted directly from the cell nucleus, which contains both coding and non-coding regions
