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 [...]
The below mentioned article provides notes on Urea Cycle. Whenever amino acids are utilised for energy production or for the synthesis of glycogen or fat, an amino group is liberated in the form of ammonia. Living organisms must have some mechanisms of removing this ammonia from the cell environment because even low concentrations of ammonia are poisonous. (Levels of only [...]
