C) SSU rRNA
D) tRNA

Question

Quizplus · Accepted Answer

SSU rRNA (Small Subunit ribosomal RNA) is commonly used in sequence-based evolutionary analyses as it is highly conserved across all living organisms, allowing for comparisons between divergent species. Additionally, the molecular clock hypothesis suggests that mutations in rRNA accumulate at a relatively constant rate over time, providing a useful tool for estimating the divergence time between species.
