1.	Which of the following is untrue about cytologic maps?(a) They cannot be directly observed under microscope(b) They refer to banding patterns(c) They can be viewed on stained chromosomes(d) They can be directly observed under microscopeThe question was posed to me during an internship interview.This intriguing question originated from Genome Mapping topic in portion Genome Mapping, Assembly and Comparison of Bioinformatics
Answer» The correct answer is (a) They cannot be directly OBSERVED under MICROSCOPE Best explanation: Cytologic maps refer to banding PATTERNS SEEN on stained chromosomes, which can be directly observed under a microscope. The observable LIGHT and dark bands are the visually distinct markers on a chromosome.
