It covers their structure, role in catalysis, and historical significance, emphasizing the RNA world hypothesis where RNA preceded proteins. The section examines examples like self-splicing introns, RNase P, and the ribosome as ribozymes, explaining their mechanisms and significance in evolution and cellular regulation.
