Question

Which of the following steps has not yet been accomplished by scientists studying the origin of life?
a. synthesis of small RNA polymers by ribozymes
b. formation of molecular aggregates with selectively permeable membranes
c. formation of protocells that use DNA to direct the polymerization of amino acids
d. abiotic synthesis of organic molecules

Accepted Answer

Hello everyone here We have a question that says blank are structures that are formed from the aggregation of a biotic components and provide insights on the origin of life. A rib enzymes. Rib enzymes are RNA molecules that have the ability to catalyze specific biochemical reaction. So it is not a be stromatolites. Stromatolites are microorganisms that produce adhesive compounds that submit sand and other rocky materials, so it is not be see proto sal's proto cells or structures that are formed from the aggregation of a biotic components and provide insights on the origin of life. So it is see and Lucas cells are a venerable ancestor that was a single celled bacterium like organism. So it is not D. So our answer here is c proto sales. Thank you for watching. Bye.
