WebIn fact, until the 1950s, the structure of DNA remained a mystery. In this article, we'll briefly explore how the double-helical structure of DNA was discovered through the work of James Watson, Francis Crick, Rosalind Franklin, and other researchers. Then, we'll take a look at the properties of the double helix itself. WebThe uppermost Erwin Formation is a fining- and thinning-upward parasequence that represents part of a transgressive systems tract. Tidal-flat and shoreface facies within northwestern thrust sheets unconformably overlie the highstand systems tract, whereas shelf facies within southeastern thrust sheets are conformable on the highstand systems …
