Problem:
DNA sequences can also be used for phylogenetic analysis, but this approach relies on the growth and cultivation of microorganisms in the lab and knowledge of specific gene products and sequences.
What is the major advantage of using small subunit ribosomal RNA (SSU rRNA) gene sequences for phylogenetic analysis over DNA sequences?
Choose the best answer.
Both SSU rRNA gene and DNA sequences are equally beneficial for phylogenetic analysis.
SSU rRNA is a better indicator of phylogeny.
Standard primers exist for SSU rRNA gene sequences. Primers are required in DNA sequence analysis, but not SSU rRNA sequence analysis. PCR products can be visualized. Please justify this.
