Scientists build models based on what they know from previous research to derive testable hypotheses. Independently, both Watson

and Crick and their competitor Linus Pauling constructed an incorrect triple helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. Although their model was wrong, what assumption made it reasonable to build a model with the bases projecting to the outside

Answer:

Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species

Explanation:

Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.

Which of the following is the most direct evidence for evolution?
Alex_Xolod [135]

Answer:

D. Fossil record.

Explanation:

The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.
