Why is understanding the structure of DNA and how it is replicated important?

As you read, think about the questions within the article and answer them in paragraph format on some of the
following questions. Note** you don’t have to answer every question but you should be writing at least a paragraph.
*Use these questions not the ones at the end of the article*

Based on parts 1 and 2:
Feel free to answer and discuss the following questions that demonstrate your understanding of the topic:
Why is understanding the structure of DNA and how it is replicated important? List some technologies and practical applications that could not have been developed without this understanding.
How does the structure of DNA identified by Watson and Crick differ from the model previously proposed by Linus Pauling and others?
What discovery by Erwin Chargaff helped Watson and Crick build their model of DNA structure? How was this piece of information helpful to them?
The conclusion of the paper published by Watson and Crick includes the now rather famous statement: “It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.” Describe what this statement means and why it is significant.
The following two questions deal more with the ethical concerns surrounding this work and should lead ot an interesting discussion!
What is the main scientific weakness you notice in Watson and Crick’s paper?
Is Watson and Crick’s acknowledgement of Franklin satisfactory, or did she deserve more credit? Explain why. ** This has been highly controversial in the scientific community!
Based on part 4:
Feel free to answer and discuss the following questions that demonstrate your understanding of the topic:
Which model(s) of DNA replication are consistent with the data collected after the first round of replication? Which model(s) can be ruled out? Why? After the second round of replication? Why?
According to the model of DNA replication identified as correct, what would the data look like after a third round of a replication? How about after a fourth round?
Why are bacteria like Escherichia coli good for studying DNA replication (as opposed to using other types of cells)?
