How does molecular taxonomy help in classification?

  1. A
    It relies only on physical characteristics
  2. B
    It classifies organisms based on genetic and protein sequence similarities
  3. C
    It eliminates the need for taxonomy
  4. D
    It is only used for extinct species

Solution & Step-by-step Explanation

Molecular taxonomy uses comparison of DNA, RNA, and amino acid sequences to identify how closely related different species are. This provides a clear genetic "signature" for classification.
