A haploid (n) spore developing into a female gametophyte in heterosporous plants.
Industry:Biotechnology
A heat-stable DNA polymerase isolated from the thermophilic bacterium <i>Thermus aquaticus,</i> and used in PCR.
Industry:Biotechnology
A heterozygote that contains two mutations arranged in a cis configuration (e.g., <i>a</i>+ <i>b+</i> / <i>a</i> <i>b).</i>
Industry:Biotechnology
A high frequency of mutation that occurs in the gene segments encoding the variable regions of antibodies during the differentiation of B lymphocytes into antibody producing plasma cells.
Industry:Biotechnology
A high-molecular-weight polymer that is composed of sugar residues and is secreted by a micro-organism into the surrounding environment.
Industry:Biotechnology
A histochemical test in which the distribution of DNA in the chromosomes of dividing cell nuclei can be observed. A tissue section is first treated with dilute hydrochloric acid to remove the purine bases of the DNA, thus exposing the aldehyde groups of the sugar deoxyribose. The section is then immersed in Schiff's reagent, which combines with the aldehyde groups to form a magenta-coloured compound.
Industry:Biotechnology
A hormone produced primarily by the corpus luteum of the ovary, but also by the placenta, that prepares the inner lining of the uterus for implantation of a fertilized egg cell.
Industry:Biotechnology
A hormone secreted by insects from a pair of endocrine glands close to the brain. It inhibits metamorphosis and maintains the larval features.
