In this article we will discuss about transposable elements in human. In human genome, two retro-transposons called LINEs (long interspersed sequences) and SINEs (short interspersed sequences) are found. LINEs are repeated sequences more than 5,000 bp long, interspersed among unique sequence DNA up to approximately 35,000 bp long. Full length LINEs are autonomous elements that encode the enzymes for their [...]
In this article we will discuss about the transposable elements in maize, peas and drosophila plants. Transposable Elements in Maize Plants: Several families of transposons were identified in corn. In each family there exist two forms of transposon: (i) Autonomous elements that can transpose by themselves and (ii) Non-autonomous elements that cannot transpose by themselves because of lacking the gene [...]
The following points highlight the three main types of transposable elements found in plasmids. The types are: 1. F-Factor 2. R-Factor 3. Bacteriophage Mu. 1. F-Factor: The transfer of genetic material between conjugating E. coli is the result of the function of a plasmid called fertility factor F. It is an extrachromosal circular double stranded DNA molecule capable of self-replication [...]
