A laboratory procedure in which a cell's nucleus is removed and placed into an oocyte with its own nucleus removed so the genetic information from the donor nucleus controls the resulting cell. Such cells can be induced to form embryos. This process was used to create the cloned sheep "Dolly".
See also: cloning.
Industry:Biology
The introduction of foreign DNA into a host cell.
See also: cloning vector, gene therapy.
Industry:Biology
Alleles carrying particular DNA sequences associated with the presence of disease..
Industry:Biology
A process by which the genetic material carried by an individual cell is altered by incorporation of exogenous DNA into its genome..
Industry:Biology
A discrete portion of a protein with its own function. The combination of domains in a single protein determines its overall function..
Industry:Biology
An experimentally produced organism in which DNA has been artificially introduced and incorporated into the organism's germ line.

Industry:Biology
A subunit of DNA or RNA consisting of a nitrogenous base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA). Thousands of nucleotides are linked to form a DNA or RNA molecule.
See also: DNA, base pair, RNA.
Industry:Biology
An allele that is almost always expressed, even if only one copy is present.
See also: gene, genome.
Industry:Biology
The process in which the genetic code carried by mRNA directs the synthesis of proteins from amino acids.
