Scientists use only certain parts pf a persons DNA to make DNA fingerprints because those parts?
contain highly variable regions that vary among individuals, making them ideal for distinguishing between different people. These parts are typically non-coding regions of DNA, known as short tandem repeats (STRs), that are prone to variations in the number of repeated sequences. By analyzing these specific regions, scientists can create a unique genetic profile for each individual based on the variations present in their DNA.

Different persons have different DNA fingerprints because?
Different persons have different DNA fingerprints because each person's DNA is unique, with variations in the sequences of nucleotide bases. These variations can occur due to genetic mutations, inheritance from parents, and recombination during reproduction. As a result, the pattern of DNA fragments produced by techniques like PCR or gel electrophoresis will differ from person to person.
Are fingerprints inherited?
No; fingerprints are not inherited. Fingerprints are unique for every person. Even identical twins do not share the same fingerprints. A Scotland Yard scientist has expressed the fact that of all the fingerprints "ever taken for any reason, we still haven't found two individuals that share the same fingerprints."Well fingerprints are not inherited but the patterns are. There have been studies that show that the fingerprint patterns of related persons are similar. The exact number, shape, and spacing of ridges changes from person to person.yes fingerprint patterns are genetic and are passed down but every ones fingerprint is unique
What are 3 practical applications of DNA fingerprints?
Forensic investigations: DNA fingerprints are used to identify suspects, victims, and missing persons in criminal cases. Paternity testing: DNA fingerprints are used to determine biological relationships between individuals, such as confirming paternity. Conservation biology: DNA fingerprints are used to study population genetics and track individuals in endangered species to inform conservation efforts.
What are fingerprint's?
Variation in humans is the pattern of ridges in the skin of the finger prints.However, fingerprints are used to hold on to things. They were not actually made to ID people. We just have come up with this ID when we realized that no two people have the same finger prints. We have used other methods to ID, including DNA tests and retinal scans.
Why do finger prints tell a person's identity?
Every person has different fingers prints. A persons finger print can be compared with each person and their identity eliminated. They are formed during the very early stages of pregnancy but their shape is NOT controlled by genes. Identical twins who have identical DNA still have different finger prints making finger prints still a more positive test than DNA.
How do fingerprints tell a persons identity?
no two people have the same fingerprints. Everyone's fingerprints is unique
Do fingerprints change over time?
No
Can the persons letter be traced by fingerprints?
Yes, fingerprints can be traced back to a person by matching them with a known fingerprint database. However, this process requires specific equipment and expertise to analyze the fingerprints accurately.
Different persons have different DNA fingerprints because?
Different persons have different DNA fingerprints because each person's DNA is unique, with variations in the sequences of nucleotide bases. These variations can occur due to genetic mutations, inheritance from parents, and recombination during reproduction. As a result, the pattern of DNA fragments produced by techniques like PCR or gel electrophoresis will differ from person to person.
How do the police find fingerprints?
To get fingerprints from a surface the police apply a fine powder (usually aluminium) to the surface where they think a print might be or where they can see one. When they blow or brush it off, the powder sticks to where the fingerprint is. They transfer this powder pattern using sticky tape to a piece of paper so they can see it more clearly. UV lights are also used by forensic scientists to illuminate fingerprints on surfaces and trace evidence on clothing such as bodily fluids and stains.
Why are fingerprints used for investigations?
Any person can be identified by examining fingerprints. No two persons have exactly the same arrangement of fingerprint patterns, and the patterns remain unchanged through a person's life.
What can be used to identify a persons fingerprints handprints face voice eye and handwritten signatures?
biometric device
How unknown persons dead body can be identified?
Fingerprints, dental records, tattoos or other distinguishing marks.
Are fingerprints inherited?

Is it true that all the persons in the world has some quality which make them different from others?
Yes. For example, it is said no two people have the same fingerprints
What are 3 practical applications of DNA fingerprints?
Forensic investigations: DNA fingerprints are used to identify suspects, victims, and missing persons in criminal cases. Paternity testing: DNA fingerprints are used to determine biological relationships between individuals, such as confirming paternity. Conservation biology: DNA fingerprints are used to study population genetics and track individuals in endangered species to inform conservation efforts.
Any examples of how fingerprints are used in law enforcement?
Well they cut out the finger print and put it through a machine and they match it with the persons record and find him/her.
