What are vntr?
VNTR stands for Variable Number Tandem Repeats, which are regions of a DNA molecule where a short nucleotide sequence is repeated multiple times. These repeat sequences vary in length among individuals, making VNTRs useful in DNA fingerprinting for identifying individuals or determining genetic relatedness.
What are short tandem repeats?
A short tandem repeat or STR is a type of polymorphism, where short sequences of DNA are repeated. It is a useful tool in forensics because the number of times a DNA sequence is repeated for a given STR varies between individuals.
Suggestions useful for fingerprinting DNA?
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.
Why can only certain parts DNA be used as DNA fingerprints?
The parts must be unique to the person.The parts must be unique to the person

DNA fingerprinting is used to identify individuals by?
analyzing unique patterns in their DNA, such as short tandem repeats (STRs). By comparing these patterns between samples, scientists can determine the likelihood of a match, which is useful in forensic investigations, paternity testing, and identifying genetic diseases.

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
What is a useful characteristic for classifying humans?
nothing
What property is most useful for the identification of sulfur?
The property most useful for the identification of sulfur is its characteristic smell, often described as similar to that of rotten eggs.
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.
What is the name of a bycycle which can be ridden by more than one person?
For two people it's a tandem. For more people you're looking at some sort of custom build, and they tend to: a) use motorcycle wheels in order to be strong enough. b) not be particularly useful in practice.
Why is fingerprinting useful?
it shows you evidence it help police to catch or keep trace of bad people like robbers , thief , pickpocket and kidnaper.
What is a characteristic of electromagnets that makes them useful in simple tools?
they are magnetic
What constant properties that are most useful in identifying a substance?
Characteristic properties.
