Question

DNA fingerprinting is based on the principle of identifying which sequence of DNA

Answer 1

Answer:

DNA fingerprinting, also called DNA typing, DNA profiling, genetic fingerprinting, genotyping, or identity testing, in genetics, method of isolating and identifying variable elements within the base-pair sequence of DNA

Answer 2

Answer:

The answer is Repetitive sequence of DNA

Explanation:

DNA Fingerprinting:

• It is a method for determining the probable identity of a person based on a particular nucleotide sequence found in certain regions of human DNA that are unique to each individual.
• It can be used in court as evidence, for identifying dead bodies, finding blood relatives, and finding cures for diseases.

Repetitive Sequence of DNA

• In DNA and RNA, repetitive sequences are nucleic acid patterns that occur multiple times throughout the genome.

Repetitive sequencing in DNA fingerprinting

• It is necessary for DNA to contain generic signals repeated over and over again so that unique code sequence files can be expressed and to perform additional functions essential to cell replication and propagation.
• In DNA fingerprinting, chromosomal or plasmid DNA fragments of different sizes can be resolved by restriction endonuclease-mediated digestion and/or DNA amplification into a band pattern that serves as a unique identification.
• A bacterial chromosome can be identified by its unique "bar codes" or DNA fingerprints without measuring gene expression or enzyme function.
