Glossary - PBS Public Broadcasting Service

Glossary - PBS Public Broadcasting Service The RNA world would have eventually been replaced by the DNA, RNA and protein world of today, likely through an intermediate stage of ribonucleoprotein enzymes such as the ribosome and ribozymes, since it is argued that proteins large enough to self-fold and have useful activities would only have come about after RNA was available to catalyze peptide lation or amino acid polymerization. Acquired trait A phenotypic characteristic, acquired during growth and development, that is not genetiy based and therefore cannot be passed on to the next.
