Problem:
Question 1: How is gene expression regulated in eukaryotes? This is a HUGE question. You should be able to discuss pre and post- transcription in various ways.
Question 2: A biologist isolated a gene from a human cell, placed it in a plasmid and inserted the plasmid into a bacterium. The bacterium made a new protein but it was nothing like the protein found in the human. Explain why.
Question 3: Why do identical twins usually become more different from each other as they age?
Could someone help to explain the answer of these questions.
