Question

A "marker" in a genetic sense usually represents a site along a chromosome where a specific nucleotide sequence exists. What specific phrase is used when such markers are identified by restriction endonucleases and a particular set of DNA fragments is generated?

Answer 1

When genetic markers are identified by restriction endonucleases and a particular set of DNA fragments is generated, it is referred to as restriction fragment length polymorphism (RFLP). Each individual will have a unique pattern of bands on gel electrophoresis, which is known as their DNA 'fingerprint'.

Step-by-step explanation:

When genetic markers are identified by restriction endonucleases and a particular set of DNA fragments is generated, it is referred to as restriction fragment length polymorphism (RFLP). RFLPs are detected when the DNA of an individual is cut with a restriction endonuclease, generating a series of DNA fragments. Each individual will have a unique pattern of bands on gel electrophoresis, which is known as their DNA 'fingerprint'.
