Structural gene identification and mapping by DNA-mRNA hybrid-arrested cell-free translation.
نویسندگان
چکیده
We present a simple method for directly correlating structural gene sequences in DNA with their corresponding mRNAs. This is based upon the fact that mRNA hybridized with its complementary DNA will not direct the cell-free synthesis of a complete polypeptide. Full translational activity of the mRNA is recovered upon the heat melting of the hybrid. Utilizing the rabbit beta globin clone PbetaG1, we demonstrate the application of hybrid-arrested translation for the identification of structural gene sequences within recombinant DNA molecules. In addition, the method is used to locate and order precisely several adenovirus 2 polypeptides within the viral genome.

R - Looping and Structural Gene Identification
The advent of recombinant DNA technology has made possible studies on the organization and expression of eukaryotic genes, which were previously restricted to prokaryotic and viral genes. In large measure, these studies exploit and are dependent upon the availability-through recombinant DNA molecules--of large amounts of individual eukaryotic DNA sequences. They are also dependent upon an accur...
متن کاملConstruction and identification by positive hybridization-translation of a bacterial plasmid containing a rat growth hormone structural gene sequence.
The construction, identification, and use of a recombinant DNA clone containing a growth hormone structural gene sequence is described. A cDNA copy of partially purified pregrowth hormone mRNA from cultured rat pituitary tumor (GC) cells was employed in the construction of a hybrid plasmid, designated pBR322-GH1. The cloned DNA sequence was positively identified by a hybridization-translation p...
متن کاملConstruction and Preliminary Characterization of the Rat Casein and a-Lactalbumin
We have constructed a double-stranded cDNA library using total poly(A)-containing RNA extracted from 8day lactating rat mammary gland and have utilized this library to isolate clones for each of the four major milk proteins. These four cDNA clones, representing the three major rat caseins and a-lactalbumin, were initially identified by colony hybridization with labeled cDNA probes synthesized f...
متن کاملP-244: Analysis of Genomic and Cell Free DNA of A let-7 microRNA Binding Site of KRAS Gene Polymorphisms in Endometriosis
Background: Endometriosis is one of the most common benign gynecological diseases which is characterized by endometriallike tissue growing outside the uterine cavity. Although the pathology of endometriosis remains unknown, the genetic predisposition plays an apparent role. Several genes have been contributed to endometriosis, but it seems KRAS has a crucial role, because its activation results...
متن کاملP-71: Construction of Required DNA Plasmids for Validation of Predicted MicroR-NA Targets
Background: The micro-ribonucleic acids (miRNAs) are noncoding RNA molecules that are conserved developmentally and include usually 18-25 nucleotides. MiRNA regulates gene expression through mRNA degradation or inhibiting of its translation. These biomolecules contribute in cellular physiologic and pathologic processes and most of them may act as oncogenes or tumor inhibitors. Identification of...
