A strain that can grow in a minimal medium containing arginine, but NOT in minimal media containing citrulline nor in minimal media containing ornithine would have a mutation in the gene that encodes for ________.

• enzyme 1.

• enzyme 2.

• enzyme 3.

• both enzymes 1 and 3.

• both enzymes 2 and 3.

Consider Possibilities: What other information is related to the question? Which information is most useful?

• The most useful information is the one directly related to answering the question.

• All information is equally useful regardless of relevance.

• Unrelated information is always the most useful.

• The least relevant information should be prioritized.

The most likely way to produce the correct answer is to use what information and/or problem-solving approach?

• Identify relevant information and apply logical reasoning

• Ignore the information provided

• Guess without analyzing the problem

• Rely solely on memorization

Reflect on Process: Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?

• Reflecting on your problem-solving process helps identify mistakes and improve future results.

• Ignoring your process is the best way to improve.

• You should never revise your approach after making a mistake.

• The process is not important in problem-solving.

A strain that can grow in minimal medium containing ornithine, citrulline, or arginine, but not in minimal medium alone would have a mutation in the gene that encodes for

• enzyme 1.

• enzymes 1, 2, and 3.

• enzyme 2.

• The strain would be the wild type with no genetic mutations.

• enzyme 3.

Given what you now know, what information and/or problem-solving approach is most likely to produce the correct answer?

• Identifying relevant information and applying logical reasoning

• Guessing randomly without using any information

• Ignoring the problem and choosing any answer

• Relying solely on intuition without analysis

Did your problem-solving process lead you to the correct answer?

• Yes, it led to the correct answer.

• No, it did not lead to the correct answer.

• I am not sure if it led to the correct answer.

• The process was not completed.

The process that produces mRNA from DNA is called

• transcription.

• translation.

• replication.

• processing.

• post-translational modification.

The processes of transcription and translation are collectively known as

• RNA processing.

• gene duplication.

• protein synthesis.

• DNA synthesis.

• gene expression.

______ is to transcription as ______ are to translation.

• RNA spliceosome; ribosomes

• RNA polymerase; ribosomes

• RNA polymerase; RNA spliceosomes

• DNA polymerase; RNA polymerase

• DNA polymerase; ribosomes
