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 yeast. In yeast the transposable element is known as Ty element which is about 5-9 kb long and includes two directly repeated terminal sequences called long terminal repeats (LTR) or deltas (δ) (Fig. 9.42). Each delta contains a promoter and sequences that are recognized by transposase. The Ty element [...]
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 [...]
