Explanation:
Satellite DNA:
Satellite DNA consists of highly repeated short DNA segments that form the basis of DNA fingerprinting. These repetitive sequences vary in length and are unique to each individual, making them ideal for identifying individuals based on their DNA profile.
Principle of DNA Fingerprinting:
- DNA fingerprinting relies on the unique patterns of satellite DNA present in an individual's genome.
- By analyzing the variations in these repetitive sequences, scientists can create a genetic profile that is specific to each individual.
Procedure:
- In DNA fingerprinting, DNA samples are extracted from different sources such as blood, skin, or saliva.
- The samples are then subjected to techniques like polymerase chain reaction (PCR) to amplify the satellite DNA sequences.
- The amplified DNA fragments are separated using gel electrophoresis and visualized to create a unique pattern of bands, which serves as the DNA fingerprint.
Applications:
- DNA fingerprinting is widely used in forensic science to identify suspects or victims based on biological evidence left at a crime scene.
- It is also used in paternity testing, wildlife conservation, and archaeological research.
In conclusion, the presence of satellite DNA as highly repeated short DNA segments forms the basis of DNA fingerprinting, allowing for the precise identification of individuals based on their unique genetic profiles.

Explanation of the Answer:Satellite DNA:- Satellite DNA is a type of non-coding DNA that consists of highly repeated short DNA sequences.- These sequences are found in the heterochromatin regions of the chromosomes and show a high degree of variability in their length and sequence composition between individuals.- Due to their highly repetitive nature and variability, satellite DNA sequences are used as markers in DNA fingerprinting.DNA Fingerprinting:- DNA fingerprinting is a technique used to identify individuals based on their unique genetic profiles.- The basis of DNA fingerprinting lies in the fact that, despite sharing a majority of their genetic information, individuals have unique differences in their DNA sequences.- These unique differences can be found in regions of the genome that contain highly variable and repetitive sequences, such as satellite DNA.- By comparing the patterns of these sequences in different individuals, it is possible to create a unique "fingerprint" that can be used for identification purposes.Why Satellite DNA forms the basis of DNA fingerprinting:- The high degree of variability in the length and sequence composition of satellite DNA allows for the identification of unique patterns in each individual's genetic profile.- Since these sequences are highly repetitive, they are easy to detect and analyze using molecular biology techniques, such as PCR (Polymerase Chain Reaction) and gel electrophoresis.- The unique patterns obtained from analyzing satellite DNA can be used as a "fingerprint" to distinguish between individuals, making it a powerful tool in forensic science, paternity testing, and other fields where individual identification is crucial.
