Q & A

What fundamental mystery of life were scientists trying to understand in the early 20th century?

Scientists were trying to understand the mechanisms of inheritance and how traits were passed down from generation to generation.

Who were the two scientists credited with discovering the structure of DNA?

James Watson and Francis Crick are credited with discovering the structure of DNA.

What technique was being perfected in the early 1950s that helped in determining molecular structures?

X-ray crystallography was the powerful technique being perfected to analyze molecular structures.

Why was there skepticism regarding DNA as the genetic material before Watson and Crick's work?

Many scientists believed that proteins, due to their complexity and variety, were more likely to be the genetic material than DNA, which seemed less interesting and more simplistic.

What significant finding did Oswald Avery demonstrate regarding DNA?

Oswald Avery demonstrated that DNA could transmit genetic information, showing that it was indeed the genetic material.

What challenge did Watson and Crick face regarding competition in their research?

Watson and Crick were concerned about competition from Maurice Wilkins and Rosalind Franklin, who were also researching DNA at King's College in London.

What was the nature of the relationship between Rosalind Franklin and Maurice Wilkins?

Franklin and Wilkins had a tense and competitive relationship, both believing they should lead the research on DNA, which complicated their collaboration.

What discovery did Watson make about a specific photograph related to DNA?

Watson recognized the significance of Photo 51, taken by Rosalind Franklin, which provided crucial information about the helical structure of DNA.

How did the structure of DNA contribute to the understanding of genetic replication?

The double helix structure revealed that the complementary nature of the bases allows for easy replication by separating the two strands and creating new complementary strands.

What impact did the discovery of the double helix structure of DNA have on biology?

The discovery opened up a new world of understanding in biology, allowing scientists to decode various mysteries of life and genetics.
