1.

2   0 expression vector Cloning vector containing DNA sequences such as a promoter, a ribosome-binding site, and transcription initiation and termination sites that allow DNA fragments inserted into the vector to be transcribed and translated. © 2005 by W.

2.

1   0 translocation Movement of a chromosome segment to a nonhomologous chromosome or to a region within the same chromosome; also movement of a ribosome along mRNA in the course of translation. © 2005 by W.

3.

1   1 reannealing In DNA, the process by which two complementary single-stranded DNA molecules pair; also called renaturation. © 2005 by W. H. Freeman and Company. All rights reserved. Pierce, B.

5.	1   0 niche The particular set of combined conditions that are habitable for a species, and define its status within an ecological community. © Nature Education Source: nature.com Meaning awaits approval from a moderator

6.

1   1 junctional diversity Addition or deletion of nucleotides at the junctions of gene segments brought together in the somatic recombination of genes that encode antibodies and T-cell receptors. © 2005 by W.

7.

1   0 dicentric bridge Structure produced when the two centromeres of a dicentric chromatid are pulled toward opposite poles, stretching the dicentric chromosome across the center of the nucleus. Eventually, the dicentric bridge breaks as the two centromeres are pulled apart. © 2005 by W. H. Freeman and Company. All rights reserved. Pierce, B. Genetics: A conceptual approach. 2nd Edition.

9.	0   0 70S initiation complex Final complex formed in the initiation of translation in bacterial cells; consists of the small and large subunits of the ribosome, mRNA, and initiator tRNA charged with fMet. Source: nature.com Meaning awaits approval from a moderator

10.	0   0 5-azacytidine A chemical that can effectively remove the methyl groups from nucleic acids. Source: nature.com Meaning awaits approval from a moderator
