Question

Cytologic maps can be considered to be of _____ resolution and hence somewhat ______ physical maps.

(a) very high, inaccurate

(b) very low, accurate

(c) very high, accurate

(d) very low, inaccurate

The question was asked by my college professor while I was bunking the class.

This is a very interesting question from Genome Mapping in portion Genome Mapping, Assembly and Comparison of Bioinformatics

Answer 1

Correct choice is (d) very low, inaccurate

The explanation: The banding patterns, however, are not always constant and are subject to change depending on the extent of chromosomal contraction. Thus, cytologic maps can be considered to be of very low resolution and hence somewhat inaccurate physical maps. The distance between two bands is expressed in relative units (Dustin units).
