E)size of the ribosomes.

Question

Quizplus · Accepted Answer

The nitrogen base sequence of rRNA is a highly conserved feature that is inherited from ancestors and is relatively slow to change over time. Comparing the sequences of rRNA between organisms can give insights into their evolutionary relatedness. This method, known as molecular phylogeny, is widely used in modern biology to trace the evolutionary history of life on Earth.
