Science / Biology / Recombinant Dna Molecules: New combinations of DNA fragments formed by cutting DNA segments from two sources with restriction enzyme and then joining the fragments together with DNA ligase. Interspecies transfer of genes usually through a vector such as a virus or plasmid.
Science / Biology / Recombinant Dna Technology: A series of techniques in which DNA fragments are linked to self-replicating forms of DNA to create recombinant DNA molecules. These molecules in turn are replicated in a host cell to create clones of MORE
Science / Genetics / Recombinant Clones: Clones containing recombinant dna molecules. See recombinant dna technologies. MORE
Science / Genetics / Junk DNA: Stretches of dna that do not code for genes: most of the genome consists of so-called junk dna which may have regulatory and other functions. Also called non-coding dna. MORE
Science / Biology / Macromolecules: Large molecules made up of many small organic molecules that are often referred to as monomers; e.g., carbohydrates, lipids, proteins, and nucleic acids. Macromolecules are polymers of monomers. MORE
Science / Genetics / Exogenous DNA: Dna originating outside an organism that has been introducted into the organism. MORE
