The inverted repeats of Tn5 are functionally different.
The inverted repeats of Tn5, which have identical restriction endonuclease cleavage patterns, have different functional properties. They differ with respect to RNA polymerase binding, full promotion of neomycin resistance, the polypeptides coded for by the repeats and their function in the transposition process. There is a week RNA polymerase binding site present in one repeat and not in the ot...
متن کاملMiniature inverted-repeat transposable elements of Stowaway are active in potato.
Miniature inverted-repeat transposable elements (MITEs) are dispersed in large numbers within the genomes of eukaryotes although almost all are thought to be inactive. Plants have two major groups of such MITEs: Tourist and Stowaway. Mobile MITEs have been reported previously in rice but no active MITEs have been found in dicotyledons. Here, we provide evidence that Stowaway MITEs can be mobili...
متن کاملTransposable Elements Are a Significant Contributor to Tandem Repeats in the Human Genome
Sequence repeats are an important phenomenon in the human genome, playing important roles in genomic alteration often with phenotypic consequences. The two major types of repeat elements in the human genome are tandem repeats (TRs) including microsatellites, minisatellites, and satellites and transposable elements (TEs). So far, very little has been known about the relationship between these tw...
متن کاملThe functional differences in the inverted repeats of Tn5 are caused by a single base pair nonhomology.
The inverted repeats of Tn5 are functionally different. One repeat codes for larger polypeptides, which are required for transposition. The other repeat has a better promoter for the neomycin resistance gene in the region of the repeat near the unique sequences. These dissimilarities are now shown to be caused by a single base pair difference. This change both creates a better promoter sequence...
متن کاملPIF- and Pong-like transposable elements: distribution, evolution and relationship with Tourist-like miniature inverted-repeat transposable elements.
Miniature inverted-repeat transposable elements (MITEs) are short, nonautonomous DNA elements that are widespread and abundant in plant genomes. Most of the hundreds of thousands of MITEs identified to date have been divided into two major groups on the basis of shared structural and sequence characteristics: Tourist-like and Stowaway-like. Since MITEs have no coding capacity, they must rely on...
