One fаcet оf the study оf the оrigin of life focuses on the nаture of the first genetic mаterial. Figure 1 describes a possible scenario, known as the RNA World Hypothesis, that could have led to the evolution of our modern-day genetic material. This hypothesis states that the first genetic material was RNA, not DNA, and a transitional period led to the emergence of DNA as the storage molecule for genetic material. The model has 3 columns and 3 rows. The column labels from left to right are: column 1: The R N A World, column 2: Evolution of the Modern World, column 3: The Modern World. The information is as follows: Column 1, row 1: Ribonucleotides produce R N A, row 2: R N A uses R N A to produce R N A, row 3: Amino Acids use R N A to produce Protein. Column 2, row 1 is blank, row 2: R N A uses Protein to produce D N A. row 3 is blank. Column 3, row 1 is blank, row 2: D N A uses Protein to produce D N A, then vertically from row 2 to row 3, D N A uses Protein to produce R N A and R N A uses Protein to produce D N A, then R N A uses Protein to produce Protein. A scientist wishes to provide experimental evidence to support the model shown in Figure 1 by demonstrating the ability to synthesize an RNA molecule. Which of the following is an alternative hypothesis that can be tested to support the World Hypothesis?
