To reconstruct the evolutionary pathways of newly discovered deep-sea organisms, researchers analyze conserved molecular sequences to estimate phylogenetic divergence.
Which of the following is commonly and correctly described as a source of molecular evidence for determining evolutionary relationships?
The amino acid sequence of the gene encoding cytochrome c
The base sequence of ribosomal RNA (rRNA)
The base sequence of histone H4 protein
The amino acid sequence of transfer RNA (tRNA)
