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 [...]
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 [...]
The following points highlight the two main types of transposable elements found in prokaryotes. The types are: 1. Insertion Sequences 2. Transposon. Type # 1. Insertion Sequences (IS): IS elements are the simplest transposable elements and are normal constituents of bacterial chromosomes and plasmids. The IS elements range in size from 768 bp to more than 5,000 bp and are [...]
