Why are restriction enzymes necessary in the DNA fingerprinting process?

because DNA is the process of getting heriderity information
Ans2:Restriction enzymes clip the DNA strand and create short fragments that can be processed. If you clip the strand at a known combination, you will know that every resulting fragment ends with that combination. Knowing the lengths of the fragments allows you to identify where that combination would be located on the complete strand.

What does a geneticist use to cut DNA at specific base sequences?
Restriction enzymes, also known as restriction endonucleases, are used to cut DNA into smaller fragments. Restriction enzymes are found in bacteria, where they act like molecular scissors by cutting up DNA from invading viruses or bacteriophages. Each restriction enzyme recognizes a specific nucleotide sequence and cuts the DNA at that site. This process makes restriction enzymes extremely useful in biotechnology where they are used in procedures such as DNA cloning, DNA fingerprinting, and genetic engineering. There are hundreds of known restriction enzymes, and each one was named for the bacteria from which it was isolated. For example, EcoRI was isolated from Escherichia coli and HaeIII from Haemophilus aegyptius.
What is meant by the term restriction digest?
Its the process of cutting DNA molecules into smaller pieces with special enzymes called Restriction Endonucleases (sometimes just called Restriction Enzymes or RE's).
After DNA is cut with a restriction enzymes how is the mixture of DNA fragments sorted?
Through the process of gel electrophoresis.
Why does extracted DNA need to be fragmented?
In preparation for the electrophoresis step in "DNA fingerprinting" the electrophoresis process cannot separate meaningfully massive molecules like whole chromosomes. By using restriction enzymes that break the chromosomes at known places DNA fragments of a wide variety of lengths that the electrophoresis process can separate meaningfully will allow a pattern to be generated that can identify different individuals.
What process is used to cut DNA into fragments?
DNA can be fragmented using restriction endonucleases or restriction enzymes. Restriction enzymes identify specific sequences within the DNA and cause cleavage generating fragments. When this digested DNA is allowed to run in gel electrophoresis fragments get separated according to their mass. When visualized under UV transilluminator, fragmented DNA can be observed as fluorescing bands.

Why ligation can be considered the reverse of the restriction enzyme process?
Restriction enzymes cuts out a specific short nucleotide sequence while as the process of ligation, DNA ligase joins them together. So ligase can be considered the reverse of the restriction enzyme process as it joins DNA fragments together instead of cutting them out.

How does a healthy body process fat?
In most people, the body is already programmed by its genetic code to produce all of the enzymes and chemicals necessary to carry out the functions necessary to process fat.
What elements in the body are necessary to process different types of sugars?
Along the way, specific enzymes are needed to process different types of sugars.
What is the process that allow millions of copies of DNA to be produced?
DNA fingerprinting
The process of DNA fingerprinting is based on what fact?
that no two people have the exact same DNA
What are the subtances needed for photosynthesis?
The light energy in photosynthesis allows water and carbon dioxide to be combined into glucose. However, enzymes are also necessary in the process.
