Which of the Following is Not Used to Help Identify

Question

Which of the following is not used to help identify individual chromosomes in a karyotype?
A)Centromere position
B)Point mutations
C)Chromosome size
D)Banding pattern on staining
E)Heterochromatin regions

Accepted Answer

Point mutations are changes in the DNA sequence of a gene, but they are not used to identify individual chromosomes in a karyotype. The other choices (centromere position, chromosome size, banding pattern on staining, and heterochromatin regions) are all important features used to distinguish one chromosome from another in a karyotype.
