- A Mainly the localized pattern of DNA methylation occurring across a single gene cluster
- B Long-range transcriptional regulation of gene clusters (e.g., globin gene cluster)
- C Mainly the removal of introns from pre-mRNA carried out by the spliceosome complex
- D Mainly the recruitment of ribosomes needed to begin translation of a mature mRNA
Correct answer: B. Long-range transcriptional regulation of gene clusters (e.g., globin gene cluster)
Explanation: LCR: regulatory element that controls chromatin accessibility and transcription of entire gene clusters over long distances (10s of kb). e.g., beta-globin LCR.
