Ribozymes - Study guides, Class notes & Summaries

MICR 271 - Module 1 TESTED QUESTIONS WITH COMPLETE SOLUTIONS What is the virus-first theory? - Answer-Viruses evolved from self-replicating amino-acid structures (ribozymes, which have enzymatic properties) before cells came to be. What is the escape theory? - Answer-Asymmetrical cell division would have allowed for a section of DNA to part from the cell and protected by a protein coat could travel to other cells. There is a theory that viruses evolved from retrotransposons (sections of D...
