1. CDNA (copy DNA)
DNA synthesized from an RNA template using reverse transcriptase .

2. CDNA library (copy DNA library)
A library composed of complementary copies of cellular messenger RNA s.

3. Complementary DNA (cDNA)
DNA that is synthesized from a messenger RNA template; the single- stranded form is often used as a probe in physical mapping .

4. Complementary DNA cloning (cDNA cloning)
A lab technique where a double-stranded cdna molecule (or dscdna ) is inserted into a cloning vector (another DNA molecule which will continue to be capable of replication after insertion of foreign material), so that the gene encoded by the cdna can be expressed (transcribed and used) or so many copies of the gene can be made.

5. Complementary DNA library (cDNA library)
A collection of all of the mRNA molecules present in a cell or organism , all turned into cdna molecules with the enzyme reverse transcriptase , then inserted into vector s (other DNA molecules which can continue to replicate after addition of foreign DNA). The library can then be probe d for the specific cdna (and thus mRNA) of interest.

6. Covalently closed circular DNA (cccDNA)
A circular molecule of double-stranded DNA which is supercoil ed, or coiled up on itself due to internal tensions, because there are no breaks in the phosphate backbone (upon which the nucleotide base s are mounted) to relieve the tensions and allow it to form an open circle.

7. Double-stranded complimentary DNA (dscDNA)
A duplex DNA molecule copied from a copy DNA template .

8. Homopolymer tailing
A lab technique where a nucleic acid homopolymer (a long chain of the same nucleotide over and over) is attached to the end of a piece of DNA as a part of DNA cloning . It is especially useful in cdna cloning to get the cdna inserted into the cloning vector -- a nucleic acid homopolymer which contains the complementary nucleotide to the cdna tail is attached to the vector, which then pairs with the tail on the cdna.

9. Hybrid-arrested translation
The prevention of an mRNA molecule from being translated into a protein by hybridizing it to its corresponding cdna or to a complementary mRNA. This is used to identify cdna molecules - the scientist puts the cdna molecule in question in a test tube with a number of mRNA molecules and observes which protein is no longer able to be made.

10. Sequence tagged site (STS)
Short (200 to 500 base pair s) DNA sequence that has a single occurrence in the human genome and whose location and base sequence are known. Detectable by PCR , STSs are useful for localizing and orienting the mapping and sequence data reported from many different laboratories and serve as landmarks on the developing physical map of the human genome. Expressed sequence tags (ESTs) are STSs derived from cdnas.
