Other Genetic Recombinations

• The process by which a gene moves from one place of chromosome to another in a genome is called as transposition. The genes involved are transposon genes or transposable elements. Insertion sequences are also a type of transposable element (of about 700 bp size) which also can cause the genetic recombinations. These DNA are used to insert a foreign DNA to an organism and also cause mutagenesis.

Genetic Engineering
Development of sophisticated procedures for isolation, manipulation and expression of genetic materials in an organism, a field is called as genetic engineering. Isolation, purification and replication of fragment of DNA through some vectors are referred as gene cloning. The plasmids and bacteriophages are used as vectors for cloning.
