In this article, I will discuss the process which creates rDNA, and its end product the recombinant protein. Hamilton O. With the successive discoveries of more restriction endonucleases, it became possible for the scientists to produce insulin in large scale quantities for diabetic patients, by using this recombinant DNA technology on the bacteria E. What is recombinant DNA: DNA or deoxyribonucleic acid is the basic hereditary material that stores all genetic information pertinent to the future functioning and development of all living organisms with few exceptions in the form of viruses.

Applications of Recombinant DNA technology
Homologous recombination provides a method for genetically modifying chromosomal DNA sequences in a precise way. In addition to the possibility of introducing small precise mutations in order to alter the activity of the chromosomal DNA sequences, such a methodology makes it possible to correct the genetic defects in genes which can cause disease.
For example, Tefhnology cultured mammalian cells, such recombinational events usually occur in Modifjcation one in ten thousand cells which have taken up the relevant targeting or correcting DNA. Thus, there is a need to develop new and improved methods of homologous recombination-mediated gene repair. The present invention is related to Applicants' discovery that induction of double stranded DNA cleavage at a specific site in chromosomal DNA induces Genetic Modification Recombinant Dna Rdna Technology Or cellular repair mechanism which leads to highly efficient recombinational events at that locus. As a result, Applicants' invention relates to methods which result in induction in cells of double stranded DNA cleavage Modificatkon a specific site in chromosomal DNA. In one embodiment, induction of a double stranded break at a Genetic Modification Recombinant Dna Rdna Technology Or of interest in chromosomal DNA of the cell is accompanied by the introduction of a targeting DNA homologous to the region surrounding the cleavage site, which results in the efficient introduction of the targeting DNA into the locus.
In a second embodiment, induction of a double stranded break at a site of interest in chromosomal DNA of the cell leads to introduction of chromosomal DNA homologous to the region surrounding the site of interest into the site of interest via gene conversion.
Latest Children's Medical Center Corporation Patents:
The present invention relates to a method of repairing a specific sequence of interest in chromosomal DNA of a cell comprising a inducing in the cell a double Genetic Modification Recombinant Dna Rdna Technology Or break at a site of interest, and b introducing into the cell targeting DNA, wherein the targeting DNA comprises 1 DNA homologous to the region surrounding the site of interest and 2 DNA which repairs the specific sequence of Rdja upon recombination between the Moification DNA and the chromosomal DNA.
The targeting DNA is introduced into the cell under conditions appropriate for introduction of the targeting DNA into the site of interest. In a second embodiment, the method of repairing a specific sequence of interest in chromosomal DNA of a cell comprises inducing in the cell double stranded cleavage at a site of interest under conditions appropriate for chromosomal DNA homologous to the region surrounding the site of interest to be introduced into the site of interest and repair of the specific sequence of interest. In a particular embodiment, the specific sequence of interest is a mutation.
The present invention also relates to a method of modifying a specific sequence in Moddification DNA click here a cell comprising a inducing in the cell double stranded cleavage at a site of interest in the specific sequence to be modified, Teamwork in the Workplace b introducing into the cell targeting DNA, wherein the targeting DNA comprises 1 DNA homologous to the region surrounding the site of interest and 2 DNA which modifies the specific sequence upon recombination between the targeting DNA and the chromosomal DNA. In a second embodiment, the method of modifying a specific sequence in chromosomal DNA of a Genetic Modification Recombinant Dna Rdna Technology Or comprises inducing in the cell double stranded cleavage at a site of interest in the specific sequence to be modified under conditions appropriate for chromosomal DNA homologous to the region surrounding the site of interest to be introduced into the site of interest and modification of the specific sequence.
The invention further relates Recombinnant a method of attenuating an endogenous gene of interest in a cell comprising a inducing in the cell double stranded cleavage at a site of interest in the endogenous gene of interest, and b introducing into the cell targeting DNA, wherein the targeting DNA comprises 1 DNA homologous to the region surrounding the site of interest and 2 DNA which attenuates the gene of interest Genetiic Genetic Modification Recombinant Dna Rdna Technology Or between the targeting DNA and the gene of interest. The invention relates to a method of introducing a mutation into a site of interest in chromosomal DNA of a cell comprising a inducing in the cell double stranded cleavage at the site of interest, and b introducing into the cell targeting DNA, wherein the targeting DNA comprises 1 DNA homologous to the region surrounding the site of interest and 2 the mutation to be introduced into the chromosomal DNA.]
