Question
1. Bacterial cells containing an F plasmid that has acquired bacterial chromosomal genes are called 2. The figure below shows the results of interrupted-mating experiments with 3 different Hfr strains. What is the order of the genes, starting with G? 3. Which of the following chromosome mutations changes the order of genes in a linkage group with no gain or loss of genes from the linkage group? 4. In eukaryotes, transcription of an mRNA molecule_ . 5. If the following DNA stand was used as a template, what would the sequence of an RNA be? True or False: Indicate whether each statement is true (T) or false (F). (3 points each) 6. Polyploid individuals have two or more incomplete sets of chromosomes. 7. Reciprocal translocations involve an exchange of chromosome segments between two nonhomologous chromosomes. S. Allopolyploidy involves the contribution of chromosomes from different species. 9. Plasmids must integrate into the host cell chromosome in order to be replicated. 10. Rosalind Franklin radioactively labeled DNA and protein in phage, and determined that DNA is transmitted to the next generation. 11. Transposable elements are flanked by indirect repeats. 12. Transposable elements are found only in prokaryotes. 13. Eukaryotic linear replication utilizes a bidirectional replication fork. 14. Both eukaryotes and prokaryotes typically have only one origin of replication. 15. Meselson and Stahl showed that DNA is replicated by a semiconservative system. 16. Prokaryotic cells have different DNA polymerases for normal DNA replication, for replicating damaged DNA, and for DNA repair. 17. Eukaryotic cells have different RNA polymerases that recognize different promoters and synthesize different classes of RNAs. 18. In transcription, all parts of the DNA molecule are transcribed into RNA.Explanation / Answer
