With this copying the code worksheet/internet assignment, I learned a few things about DNA and how to tell the difference between observations, opinions, and inferences. I sorted though all the clues in my mind and decided which ones represent solid evidence of DNA replication and transcription/translation. For example, When DNA from a virus is injected into a bacterium, the bacterium produces viral protein and thats evidence supporting transcription/translation.
4. Write an explanation detailing why this clue represents solid data and is not an opinion or an inference.
Clue 8 is solid data and not an opinion or an inference because it explains what they saw and what happened step by step and what it was with what was happening by saying the bacteria with heavy DNA, when it was transferred to a culture tube with lighter nitrogen, did form DNA molecules that were made of half heavy and half light. It gives reasons and it explains what happened therefor, it IS solid fact and NOT opinion OR inference.
5. a) Why is it difficult to tell the difference between an observation and an inference?
It is hard to tell the difference between an observation and an inference because an inference is a conclusion or a deduction based on observations and an observation is data collected with any of the senses or tools such as graduated cylinders, dalliances, rulers or pH meters.
b) Which of the clues included in the table is an inference?
Clue 9, It also goes step by step in what happened and kinda how it happened also.
c) Which of the clues included in the table is an opinion?
Clue 10, it seems like it is just a statement made with only some knowledge of DNA.
6. Francis Crick was the first to recognize that information flows from DNA to RNA to protein. This concepts known as the Central Dogma. At the time the Central Dogma was first stated, it was an inference based on observations. Explain why.
Because no one knew for real weather it was that way or not. No one actually looked yet so they just guessed.
