Why is the Internal Transcribed Spacer region a useful tool for building fungal phylogenies based on sequencing data? Group of answer choices It appears in most fungi because it is sandwiched between very important regions that code for pieces of the ribosome, so this region is conserved. Within the ITS region, the nucleotides are highly variable between species. Both A and B are true.

DNA sequences called Interspaced transcribed spacer regions (ITS) are used to accurately identify fungi.

The nuclear ribosomal operon is frequently a target for microbial identification. In bacteria the small subunit, also known as 16S is often used. In eukaryotes the small subunit is known as 18S, however, 18S is not used for fungal identification at the species level. Why is this?

The universal phylogenetic tree of life shows the divergence of Bacteria, Archaea, and Eukarya. Studies of Lokiarchaeota help to elucidate these relationships, but the first universal tree of life was constructed by Carl Woese using ribosomal RNA sequences. There are advantages to using different types of nucleic acid for different types of analyses. What is a specific advantage of using small subunit ribosomal RNA (SSU rRNA) gene sequences for phylogenetic analysis compared with DNA sequences? A) Standard primers exist for SSU rRNA gene sequences, including universal primers. B) SSU rRNA is frequently transferred through horizontal gene transfer, whereas DNA sequences are not. C) Primers are required in DNA sequence analysis, but not for SSU rRNA sequence analysis. D) Although PCR products can be visualized with SSU rRNA, this is not the case with other forms of nucleic acids. E) SSU rRNA sequences accumulate mutations more rapidly than protein-encoding DNA. F) DNA sequences are too highly conserved to work well for sequence analysis; individual species are difficult to distinguish.
