Which of the Following Experimental Assemblies Provides the LEAST Compelling

question 65

Multiple Choice

Which of the following experimental assemblies provides the LEAST compelling evidence that life processes are often self-directed?

• A)The 1955 observation that tobacco mosaic virus spontaneously assembles.
• B)Nomura's 1960's experiment demonstrated spontaneous assembly of a bacterial 30S ribosomal unit from 21 purified proteins and ribosomal RNA.
• C)Removal of protein S16 from the bacterial 30S ribosomal protein/RNA mix in Nomura's experiment prevented self-assembly, providing evidence that the assembly is self-directed and sequential steps are essential.
• D)Bacterial ribosome assembly is achieved inside cells in as little as 10 minutes, while in vitro 2 hours at elevated temperatures is required.
