What are two ways to group plants?
1. classical taxonomy 2. Molecular analysis & DNA fingerprinting
The use of RFLPs for genetic fingerprinting is based on?
The use of RFLPs in generic fingerprinting is based on the ability of restriction enzymes to dissect DNA into small fragments. There are many kinds of restriction enzymes made to cut various DNA sequences.
Describe the steps in DNA fingerprinting?
steps of dna fingerprinting1.collection of cell.2.extraction of dna frm cell3.amplefication of dna4.cutting of dna5.gel electropherosis6.southern blotting7.hybridisition8.autoradiogram
How does gel electrophoresis is used to make a DNA fingerprint?
Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.
Is it impossible to link a hair to any one individual at a crime scene?
Genetic fingerprinting can match a hair to an individual person. It's now a common method of crime detection, if the root of the hair is with the hair. DNA can be extracted from the root.
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
What are two ways to group plants?

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 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.
Fragments of DNA as a form of identification?

Is DNA fingerprinting worthy?
Yes, to make the world safer. DNA fingerprinting prevents identity theft and some corruptness.
