Understanding the RNA World Hypothesis

DNA was the first genetic material, and proteins came later.

RNA was the original genetic material that could both store information and catalyze reactions.

Proteins were the first molecules to carry genetic information.

Lipids were responsible for the origin of life.

By suggesting that proteins appeared before RNA.

By proposing that RNA molecules could replicate themselves and catalyze reactions.

By stating that DNA was always present.

By ignoring the role of genetic material.

DNA polymerase

Ribozymes

Ribosomes made only of proteins

Lipid membranes

DNA is less stable than RNA.

DNA is more stable and better at storing genetic information long-term.

RNA cannot form double-stranded structures.

DNA cannot replicate.

Its rigid, double-stranded structure

Its ability to fold into complex three-dimensional shapes

Its lack of functional groups

Its inability to interact with other molecules
