This short slide set relates the role of RNA in the processes of transcription and translation to RNAís evolutionary history and the remnants of the RNA world. Save the slide set to your computer to view the explanation and notes that go along with each slide.

Use this resource to relate evolutionary concepts to the topics of transcription and translation (or get more suggestions for incorporating evolution throughout your biology syllabus). Incorporate these slides immediately after youíve discussed transcription and translation.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Life forms of the past were in some ways very different from living forms of today, but in other ways very similar.
- An organismís features reflect its evolutionary history.
- Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
- Evolution results from mutations.
- Natural selection and genetic drift act on the variation that exists in a population.
- Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing.
- Natural selection is capable of acting at multiple hierarchical levels: on genes, on cells, on individuals, on populations, on species, and on larger clades.
