Anchorage dependence describes the need of normal eukaryotic cells for a surface to attach to in order to grow in culture. Aneuploid chromosome constitution differes from the usal diploid constitution by loss or duplication of chromosomes or chromosomal segments. Annealing is the pairing of complementary single strands of DNA to form a double helix. Antibody is a protein (immunoglobulin) produced by B lymphocyte cells that recognizes a particular foreign ‘antigen,’and thusw triggers the immune response. Anticoding strand of duples DNA is used as a template to direct the synthesis of RNA that is complementary to it. Antigen is any molecule whose entry into an organism provokes synthesis of an antibody (immunoglobulin). Antiparallel strands of the double helix are organized in opposite orientation, so that the 5’ end of one strand is aligened with the 3’ end of the other strand. Antitermination proteins allow RNA polymerase to transcribe through certain terminator sites. Ap endonucleases make incisions in DNA on the 5’ side of either apurinic or apyrimidinc sites. Apoinducer is a protein that binds to DNA to switch on transcription by RNA polymerase. Archebacteria comprise a minor line of prokaryotes, and may have introns in the genome. Ascus of a fungus contains a tetrad or octad of the (haploid) spores, representhing the products of a sihngle meiosis. att sties are the loci on a phage and the bacterial chromosome at which recombination integrates the phage into. or excises it from , the bacterial chromosome. Attenuation describes the regulation of termination of transcription that is involved in controlling the expression of some bacterial operons. Attenuator is the terminator sequence at which attenuatioj occurs. Autogenous conhtrol describes the action of a gene product that either inhibits (negative autogenous control) or activates (positive autogenous control) expression of the gene coding for it. Autonomous controlling element in maize is an active transposon with the ability to transpose (cf nonautonomous controlling element). Autoradiography detects radioactively labeled molecules by their effect in creating an image on pholtographic film. Autosomes are all the chromosomes except the sex chromosomes; a diploid cell has two copies of each autosome. Blymphocytes (or B cells) are the cells responsible for synthesizing antibodies
