00:01
So we want to match the researcher with the discovery that was made.
00:05
So first one took x -ray diffraction pictures used in constructing the structure of dna.
00:12
That was rosalind franklin and maurice wilkins.
00:24
That matches with letter i.
00:28
So the next one is determined that dna contains nitrogenous bases.
00:34
That is causal, which is letter a.
00:42
Number three is identified dna as the genetic material in a bacteriophage.
00:48
That is hershey and chase.
00:53
They were able to figure out that a bacteriophage injected its genetic material into a bacteria and not its protein coat.
01:00
That corresponds to letter f.
01:05
Number four, discovered regularity in the ratios of different bases in dna.
01:13
That was chargaff.
01:16
He was the guy that came up with a pairs with t and g pairs with c, letter j.
01:27
Determined that dna is responsible for transformation in bacteria.
01:32
That was avery, mcleod, and mccarty, which is letter g.
01:52
They actually piggybacked off an experiment that somebody else did that we'll see later on in the list.
02:00
Determined worked on the helical structure of dna by building models...
