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 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 [...]
The following points highlight the six common types of DNA markers. The types are: 1. Single-nucleotide Polymorphism 2. Short Tandem Repeats 3. Variable Number Tandem Repeats 4. Restriction Fragment Length Polymorphism 5. Randomly Amplified Polymorpohic DNA 6. Amplified Fragment Length Polymorphism. Type # 1. Single-nucleotide Polymorphism (SNPs or "Snips"): The single-nucleotide polymorphism is a single base-pair change or a point [...]
