MCAT Biological and Biochemical Foundations of Living Systems Flashcards: 1c Mutations Inborn Errors

Study 1c Mutations Inborn Errors in MCAT Biological and Biochemical Foundations of Living Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Which mutation type is most likely to produce a premature stop codon: missense or nonsense?

Tap card or press Space to flip

ANSWER

Nonsense. Nonsense mutations directly change a sense codon to a stop codon, unlike missense which alters amino acids without stopping translation.

Practice questions

1 of 50Practice questions for this set
A patient has episodic weakness triggered by fasting. Labs during an episode show hypoketotic hypoglycemia and elevated medium-chain acylcarnitines. Sequencing reveals a mutation that reduces medium-chain acyl-CoA dehydrogenase (MCAD) activity. Using the concept of impaired ββ-oxidation limiting acetyl-CoA production, which outcome is most consistent?
