In this chapter, we first focused on the information that showed DNA to be the genetic material and then discussed the structure of DNA as proposed by Watson and Crick. We concluded the chapter by describing various techniques developed to study DNA. Along the way, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, what answers would you propose to the following fundamental questions:
(a) How were scientists able to determine that DNA, and not some other molecule, serves as the genetic material in bacteria and bacteriophages?
(b) How do we know that DNA also serves as the genetic material in eukaryotes such as humans?
(c) How was it determined that the structure of DNA is a double helix with the two strands held together by hydrogen bonds formed between complementary nitrogenous bases?
(d) How do we know that G pairs with C and that A pairs with T as complementary base pairs are formed?
(e) How do we know that repetitive DNA sequences exist in eukaryotes?
We need at least 10 more requests to produce the solution.
