A) a place where a restriction enzyme cuts DNA
B) a chart that traces the family history of a genetic trait
C) a particular nucleotide sequence whose inheritance can be followed
D) a radioactive probe used to find a gene
A genetic marker is _____.?
C
Definitely not B, although you might use a genetic marker in a pedigree. A and D rely on a specific nucleotide sequence, so they are encompassed in answer C.
Reply:the correct ans is D...genetic markers are usually inserted into a plasmid which is then inserted into the host cell....the best example of a genetic marker is GFP protein which glows under UV light.
