1. 2-aminopurine
A derivative of purine which can substitute for adenine during DNA replication . As a result, it can induce mistakes in DNA and is therefore a powerful mutagen .

2. 3'-azido-3'-deoxythymidine (AZT)
An antibiotic used to treat infection by HIV (the AIDS virus ). The drug works by blocking replication of the HIV genetic material (in this case it is composed of RNA rather than DNA ) by preventing the viral RNA from inserting into the host DNA.

3. Alkylating agent
A substance which contains an alkyl (derived from an alkane ) radical , with which it can replace a hydrogen atom with itself in an organic compound. As a result, it can act on DNA and interfere with replication , making it useful for destroying cells such as cancer cells.

4. Bidirectional replication
A type of DNA replication where replication is moving along in both directions from the starting point. This creates two replication fork s, moving in opposite directions.

5. Binary fission
Division of a cell into two daughter cells after DNA replication and nuclear division ( mitosis ). A form of asexual reproduction .

6. Cell
The smallest membrane-bound biological unit capable of replication. Cells can function cooperatively as a part of a tissue or organ or can function independently as free-living microorganisms.

7. Cloning vector
A DNA molecule originating from a virus , a plasmid , or the cell of a higher organism into which another DNA fragment of appropriate size can be integrated without loss of the vectors capacity for self-replication; vectors introduce foreign DNA into host cells, where it can be reproduced in large quantities. Examples are plasmids, cosmid s, and yeast artificial chromosome s; vectors are often recombinant molecules containing DNA sequences from several sources.

8. 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.

9. Conservative replication
replication of DNA in such a way that the original parent strands of the DNA molecule end up back with each other. The entire preexisting double-stranded DNA molecule is conserved during each round of replication. Compare semiconservative replication .

10. Copy number
* The number of copies of a particular sequence of DNA , a particular gene , or a particular set of genes, in the haploid genome of an organism. * The number of plasmid s per bacterium . Plasmids which are replicated easily and often are called "high-copy-number plasmids"; plasmids which are more strictly controlled in their replication are called "low-copy-number plasmids." The different types have different uses to a geneticist.
