Question

How are the genetic and the physical maps assigned on the genome?

(a) Based on microsatellites

(b) Based on macrosatellites

(c) Based on kinetochores

(d) Based on centromeres

This question was posed to me at a job interview.

Question is from Molecular Basis of Inheritance topic in division Molecular Basis of Inheritance of Biology – Class 12

Answer 1

The correct answer is (a) Based on microsatellites

The explanation: The genetic and the physical maps on the genome are assigned based on microsatellites. They are also assigned based on the act of polymorphism at the restriction endonuclease recognition sites. The repetitive DNA sequences are called as microsatellites.
