Study Guide 10 Gene Expression After these lectures, you should be able to: Answer the following questions from your textbook o Chapter 14 1, 4, 5, 12, 20, 21, 22 o Chapter 15 5, 6, 16, 17, 21, 22, 23, 29, 30, 31, 32 Compare and contrast basal transcription factors and transcriptional activator proteins Explain how enhancers work in eukaryotic DNA Explain how eukaryotic mRNA is processed before it leaves the nucleus. Describe alternative splicing Describe the structure and function of tRNA. Given a sequence of bases in DNA, predict the corresponding codons transcribed on mRNA and corresponding anticodons of tRNA. Explain the relationship between codons and anticodons Explain the relationship that exists between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide Explain the genetic code degeneracy Describe the wobble effect. Describe the structure and function of a ribosome.
