The most common examples are bacteria. A complex biological molecule composed of a chain of units called amino acids. Protein engineering A technique used in the production of proteins with new or artificial amino acid sequences. Protoplast A plant or bacterial cell that has had its cell wall removed. Recombinant DNA DNA that is formed through combining DNA from two different sources.
Humans direct the formation of recombinant DNA through selective breeding and genetic engineering.
The laboratory manipulation of DNA in which DNA, or fragments of DNA from different sources, are cut and recombined using enzymes. This recombinant DNA is then inserted into a living organism. The formation of new combinations of genes. In microbes, genetic material is recombined naturally during conjugation. The process of growing an entire plant from a single cell or group of cells.
