About 3% or so of the human genome has highly repetitive sequences or simple-sequence DNA or simple sequence repeats or satellite DNA. It does not encode proteins or RNAs but have identifiable functional importance owing to their presence in centromeres and telomeres; which makes option B wrong as genetic engineering mainly aims at transfer of genes producing desired products. Satellite DNA show relative uniformity within species and great variability between closely related species. This DNA polymorphism is revealed during DNA finger printing in identification of suspect. For the purpose, restriction enzyme digested DNA samples are sorted by gel electrophoresis followed by southern blotting. Finally, radioactive probes are washed over the nylon surface to allow their joining to any DNA fragments of same composition. Correct option is A. Sex determination in human is governed by presence or absence of Y-chromosome, not by satellite DNA which makes option D wrong. Organ transplantation mainly aims at immune system; option C is wrong.
So, the correct answer is 'Forensic science'

Satellite DNA in Forensic Science
Satellite DNA refers to a type of repetitive DNA sequence that is present in eukaryotic genomes. This DNA is composed of short, tandemly repeated units that can vary in length from a few base pairs to several hundred base pairs. Satellite DNA is not found in prokaryotic genomes.
Satellite DNA has proven to be a useful tool in forensic science, particularly in DNA profiling and identification. Here's how:
1. DNA profiling: DNA profiling is a technique used to identify individuals based on their unique DNA patterns. Satellite DNA is one of the types of DNA sequences that are analyzed in DNA profiling. By analyzing the number and size of the repetitive units in satellite DNA sequences, forensic scientists can create a DNA profile that is unique to each individual.
2. Identification of human remains: In cases where the identity of human remains is unknown, satellite DNA can be used to establish the identity of the person. This is done by comparing the DNA profile of the remains with the DNA profiles of family members or other known individuals.
3. Paternity testing: Satellite DNA can also be used in paternity testing to determine the biological father of a child. This is done by comparing the DNA profiles of the child, the alleged father, and the mother.
4. Criminal investigations: In criminal investigations, satellite DNA can be used to link suspects to crime scenes. By analyzing DNA samples found at the crime scene, forensic scientists can create a DNA profile of the perpetrator. This profile can then be compared to the DNA profiles of suspects to identify the perpetrator.
In conclusion, satellite DNA has proven to be a valuable tool in forensic science, particularly in DNA profiling and identification. Its ability to provide unique DNA patterns for each individual has made it an indispensable tool for criminal investigations, paternity testing, and identification of human remains.

Satellite DNA is useful tool ina)Organ transplantationb)Sex determinat...
The correct answer is D) Forensic science.
Explanation:
Satellite DNA, also known as repetitive DNA, is a type of DNA sequence that is repeated several times in a genome. It does not code for proteins but plays an essential role in chromosome structure and function. Satellite DNA is a useful tool in forensic science for several reasons:
1. DNA profiling: Satellite DNA is highly polymorphic, which means it varies extensively among individuals. This variability makes it an excellent tool for DNA profiling, which is used to identify individuals from biological samples such as blood, semen, hair, and saliva. By comparing the satellite DNA profiles of a suspect and a crime scene sample, forensic scientists can determine if the suspect was present at the scene of the crime.
2. Paternity testing: Satellite DNA is also useful in paternity testing, where it is used to determine the biological relationship between a child and its alleged father. By comparing the satellite DNA profiles of the child and the alleged father, forensic scientists can determine the probability of paternity.
3. Identification of human remains: Satellite DNA can also be used to identify human remains in mass disasters, such as earthquakes or terrorist attacks. By comparing the satellite DNA profiles of the remains with those of the missing persons, forensic scientists can help to identify the victims.
4. Wildlife conservation: Satellite DNA can also be used in wildlife conservation to identify and track endangered species. By analyzing the satellite DNA of animals, scientists can determine their genetic diversity and relatedness, which can help in conservation efforts.
In conclusion, satellite DNA is a useful tool in forensic science for DNA profiling, paternity testing, identification of human remains, and wildlife conservation.
