A DNA fingerprint is 'taken' by removing the genetic material from a cell. This genetic material consists of DNA bases which are sorted into groups. The DNA bases are then cut and some radioactive nucleutides added. The radioactive DNA is then collected and is ready for analysis.

How are radioactive probes useful for DNA fingerprinting?
Radioactive probes are useful for DNA fingerprinting because they can bind specifically to complementary DNA sequences, allowing scientists to visualize the DNA fragments on an X-ray film. This helps in identifying unique DNA patterns and comparing them between individuals for forensic or paternity testing purposes. Additionally, radioactive probes are highly sensitive and can detect small amounts of DNA, making them a powerful tool for genetic analysis.
What is used to copy dna for dna fingerprinting?
Nuclear transfer
What characteristic of short tandem repeat DNA makes it useful for DNA fingerprinting?
Short tandem repeat DNA is useful for DNA fingerprinting because it contains repeating sequences of 2-6 base pairs that can vary in length between individuals. This variation creates unique DNA profiles that can be used to differentiate between individuals. The high variability and stability of STRs make them ideal for forensic analysis and paternity testing.
Why did the invention of pcr make DNA fingerprinting possibe?
The invention of PCR made DNA fingerprinting possible by allowing scientists to quickly and efficiently amplify specific regions of DNA. This amplification is crucial in generating enough DNA for analysis and comparison in DNA fingerprinting techniques. PCR revolutionized DNA analysis by enabling the identification of unique DNA profiles for individual identification.
How is dna and the gel electrophoresis method useful in science?
DNA and gel electrophoresis are useful in science for analyzing and separating DNA fragments based on size. This technique is valuable in molecular biology for identifying genetic variations, determining paternity, diagnosing genetic disorders, and conducting DNA fingerprinting. Gel electrophoresis allows researchers to compare DNA samples, study gene expression, and track the progress of genetic engineering experiments.
Why do humans feel it is necessary to pursue fingerprinting?
DNA fingerprinting offers a technique to single out an individual with a 100% success rate. A persons DNA fingerprint is unique and this quality becomes very useful in forensic applications. Therefore, there is much interest in DNA fingerprinting. In research however, fingerprinting is used to differentiate between different strains of a certain species of bacteria for epidemiological studies
Is DNA fingerprinting good or bad?
DNA fingerprinting is a useful tool for identifying individuals and establishing paternity. It can be beneficial in solving crimes, confirming relationships, and identifying genetic disorders. However, concerns regarding privacy, misuse of genetic information, and potential for errors exist, so it is important to use DNA fingerprinting responsibly.
Explain how a DNA fingerprinting produced?
In DNA fingerprinting, enzymes are used to cut the DNA in the smaple found at the crime scence
How are radioactive probes useful for DNA fingerprinting?
Radioactive probes are useful for DNA fingerprinting because they can bind specifically to complementary DNA sequences, allowing scientists to visualize the DNA fragments on an X-ray film.

Additionally, radioactive probes are highly sensitive and can detect small amounts of DNA, making them a powerful tool for genetic analysis.
Why is DNA fingerprinting unreliable?
DNA fingerprinting is not as reliable as regular DNA profiling. Statistics show that about one out every 800,000 people have the same DNA fingerprint.
