Genetic engineering

Genetic engineering

The science of modifying and manipulating genes to create new artificial DNA or synthetic genes of different organisms. There are many purposes for genetic engineering, some of which include finding better treatment for diseases, or simply for discovering new organism of interest.

Genetic engineering

coding sequence

Biotechnology; Genetic engineering

That portion of a gene which directly specifies the amino acid sequence of its protein product. Non-coding sequences of genes include control regions, such as promoters, operators and terminators, as ...

satellite DNA

Biotechnology; Genetic engineering

That portion of the DNA in plant and animal cells consisting of highly repetitious sequences (millions of copies) typically in the range from 5 to 500 bases. Thousands of copies occur tandemly ...

Dolly

Biotechnology; Genetic engineering

The (name of the) first mammal to be created by cloning a cell from an adult animal. In this particular case, the cell came from the mammary tissue of an adult ewe. The creation of Dolly showed that ...

tailing

Biotechnology; Genetic engineering

The in vitro addition of the same nucleotide by the enzyme terminal transferase, to the 3´-hydroxyl ends of a duplex DNA molecule. a.k.a. homopolymeric trailing.

pollen culture

Biotechnology; Genetic engineering

The in vitro culture and germination of pollen grains. Callus cultures thus obtained will form shoots or embryoids which develop into monoploid plants.

cell culture

Biotechnology; Genetic engineering

The in vitro growth of cells derived from multi-cellular organisms. The cells are usually of one type.

antisense therapy

Biotechnology; Genetic engineering

The in vivo treatment of a genetic disease by blocking translation of a protein with a DNA or an RNA sequence that is complementary to a specific mRNA.
