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 [...]
In this article we will discuss about:- 1. Meaning of DNA Fingerprinting 2. Basis of DNA Fingerprinting 3. Applications. Meaning of DNA Fingerprinting: Presence or absence of restriction sites in the genome can be used as genetic markers. Similarly, another type of variation in the length of repetitive DNA sequence cluster may be used for a wide variety of genetic [...]
In this article we will discuss about:- 1. Meaning of Recombinant DNA Technology 2. Basic Steps in Recombinant DNA Technology 3. Preparation. Meaning of Recombinant DNA Technology: In nature, exchange of information between two genetic materials resulting in acquisition of new segments of DNA by a genome is very common, but it occurs only among genetic materials of the same [...]
