IB Biology: A2.1-RNA First Hypothesis Evidence

Front

What ability of short RNA sequences supports the RNA first hypothesis?

Back

Short RNA sequences can duplicate into other molecules of RNA, demonstrating that RNA can self-replicate.

Front

How does RNA's catalytic activity support the RNA first hypothesis?

Back

RNA's catalytic activity suggests it may have acted as both the genetic material and the enzymes of the earliest cells.

Front

What role do ribozymes in the ribosome play in supporting the RNA first hypothesis?

Back

Ribozymes in the ribosome catalyze peptide bond formation during protein synthesis, indicating RNA's catalytic capabilities.
