Discuss gene expression and describe the functions of various non-coding RNAs.

1. In your own words, describe the process of DNA replication in detail, including the names and functions of all proteins involved. 2. Sometimes DNA is damaged or copied incorrectly. How is DNA proofread? If anomalies are detected, how can DNA be repaired? Give specific examples. 3. Discuss eukaryotic chromatin packing in detail. Describe the successive layers of organization that result in the significant consolidation of the chromatin. 4. Describe the detailed changes to the mRNA molecule during eukaryotic post-transcriptional RNA processing, which occurs after transcription, but before translation. 5. Discuss gene expression and describe the functions of various non-coding RNAs.
