Unformatted text preview: 11-13-09 Quiz 11 True (a) or False (b): 1. If a RNA transcript reads 3’UACGAA5’, its DNA template strand will read 5’ATGCTT3’, and the DNA coding strand will read 3’TACGAA5’. 2. Beadle and Tatum’s hypothesis has been updated to: “One gene – one protein”. 3. Transcription factors are proteins that prokaryotes need for helping bind RNA polymerase to the promoter site of a gene. 4. A polyadenylation signal is transcribed into the pre-mRNA of prokaryotes. 5. A gene is a region of DNA whose final product is either a polypeptide or an RNA molecule, and it includes non-transcribed sequences. 6. If a mRNA codon reads 3’AUG, the corresponding tRNA anticodon sequence should be 3’TAC. 7. The “poly-A” sequence on eukaryote mRNA is located on the 5’ end. 8. Spliceosomes are assembled from proteins + a type of RNA called snRNA. 9. Alternative RNA splicing allows the number of different proteins an organism can produce to be greater than its number of genes. 10. Polypeptide synthesis always begins in the cytosol, but those destined for the endoplasmic reticulum or for secretion are marked by a “signal peptide/recognition particle”. Key: 1a, 2b, 3b, 4b, 5a, 6b, 7b, 8a, 9a, 10a ...
