In DNA fingerprinting, the DNA probe that is used is ______to the DNA sequence of the repeats in the sample?
im guessing amplify????
Actually, in DNA fingerprinting, the DNA probe that is used is complementary to the DNA sequence of the repeats in the sample, not amplified.
To explain further, DNA fingerprinting is a technique used to identify and compare DNA samples. One of the methods used in DNA fingerprinting is called Southern blotting. This technique involves cutting the DNA into smaller fragments using restriction enzymes, separating the fragments on a gel through a process called gel electrophoresis, and then transferring the fragments onto a filter membrane.
Once the DNA fragments are transferred onto the filter membrane, a DNA probe is used to detect specific sequences of DNA. A DNA probe is a short, single-stranded DNA molecule with a complementary sequence to the target DNA sequence of interest.
Therefore, the DNA probe used in DNA fingerprinting is designed to bind specifically to the repeat sequences present in the sample DNA, allowing scientists to identify and analyze these specific regions.
