The care and management of property.  

An individual having a homozygous gene pair. An organism in which the corresponding genes (alleles) on the two genomes are identical. An organism which possesses an identical pair of alleles in regard to a given (genetic) characteristic. An organism whose chromosomes carry identical members of any given pair of genes. The gametes are, therefore, all…

Adhesion between neutrophils.  

Proteins encoded by homeobox genes that exhibit structural similarity to certain prokaryotic and eukaryotic DNA-binding proteins. Homeodomain proteins are involved in the control of gene expression during morphogenesis and development (gene expression regulation, developmental).  

Distinctive sequence of DNA bases. A short sequence of DNA that is 1 80 base pairs long and located in the 3′ exon of certain genes of the Drosophila fly (where they were discovered by Walter Gehring during the 1970s). In the 1980s, Jani Christian Nusslein-Volhard discovered that one homeobox was attached (in adjacent exon)…

Hydrolyzes N-acetyl groups on histones.  

An essential amino acid important in a number of metabolic processes. It is required for the production of histamine. An essential amino acid with a basic side chain. A basic amino acid that is essential in the nutrition of the rat. It is formed by the decomposition of most proteins (as globin). An amino acid…

Enzymes that catalyze the transfer of hexose groups.  

Having unlike alleles at one or more corresponding loci on homologous chromosomes. An individual organism with different alleles at one or more particular loci. In genetics, an organism with unlike members of any given pair of series of alleles which consequently produces unlike gametes. An individual having unlike copies of a gene coding for a…

Pertaining to organisms that are consumers and dependent on other organisms for their source of energy (food). A plant that obtains starch from sources other than photosynthesis. Organisms that must obtain some or all of their food from external sources. In general, applied to animals and non-photosynthetic plants, heterotroph. Describing organisms (known as heterotrophs) that…
