Explanation of DNA finger print ar the cellular/DNA
DNA fingerprinting = DNA
It is a molecular biology method used to detect differences in the DNA sequence that are diagnostic for a given individual. Humans contain a large genome. Most of the human genome contains non-coding segments. these noncoding segments exhibit a greater polymorphism as compared to the coding regions. These polymorphisms are highly variable and can be unique to each individual i.e. these polymorphisms can be used to the identity of an unknown DNA sample. These polymorphisms include SNP, inversions, deletions, or duplications. They can be detected by PCR and restriction digestion.
Some of the commonly used DNA markers are SSLP, RAPD, RFLP, and VNTR.
