During phylogenetic studies which of the following is sequenced?
Options
- ArRNA
- BmRNA
- Cmitochondrial RNA
- DtRNA
Correct answer
A. rRNA
Step-by-step solution
The study of relationships between different groups/species of organisms and their evolutionary development is called phylogeny. It helps in determining the ancestry and evolutionary history of all life forms on Earth. One of the RNA found in the cell that helps in translation by supporting the protein synthesis organelle ribosomes is the ribosomal RNA (rRNA) which is sent to the cytoplasm from nucleus. rRNA varies between species due to mutation and using its sequence can trace the evolutionary relationships.
