Dna technology producing dna fragments development of technology that allows genes to be manipulated, altered and transferred from organism to organism, even transform dna itself, has become very advanced in recent years. The use of recombinant dna technology recombinant dna technology is the technology of preparing recombinant dna in vitro by cutting up dna molecules and splicing together fragments from more than one organism(1) this is the process of using recombinant dna technology to enable the rapid production of human protein from a single gene of insulin. Dna and molecular biology has advanced by leaps and bounds it has found use in pharmacology, genetic engineering in disease prevention, in increasing agricultural growth, in detection of disease. Recombinant dna and the transgenic technology that it spawned have already entered everyday lives to a degree, as evidenced by the completion of a draft of the human genome sequence, criminal trials relying on dna evidence, and controversy over the use of genetically modified corn and other organisms.

Dna sequencing: dna sequencing, technique used to determine the nucleotide sequence of dna (deoxyribonucleic acid) the nucleotide sequence is the most fundamental level of knowledge of a gene or genome it is the blueprint that contains the instructions for building an organism, and no understanding of genetic. Gene transfer is a technique to stably and efficiently introduce functional genes (that are usually cloned) into the target cells genetic transfer is the mechanism by which dna is transferred from a donor to a recipient. Recombinant dna technology, joining together of dna molecules from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industrysince the focus of all genetics is the gene, the fundamental goal of laboratory geneticists is to isolate, characterize, and manipulate genes.
