Flashcard 178: β-thalassemia is often due to mutations in _____ and promoter sequences
Answer: splice sites
Extra: β-thalassemia is typically caused by point mutations in the β-globin gene (in contrast to α-thalassemia, which is usually caused by gene deletions).
Mechanisms:
* **Splice site mutations**: Lead to defective mRNA processing (can result in β⁰ or β⁺ thalassemia).
* **Promoter mutations**: Lead to decreased initiation of transcription (typically result in β⁺ thalassemia).
Note: Nonsense mutations (leading to premature stop codons) can also cause β-thalassemia, but they occur in the coding regions (exons), not the promoter.
Flashcard 179: Dopamine in the synapse is transported back into the nerve terminal via the _____ transporter
Answer: (DAT) dopamine
