- Although DNA transposons are abundant in the genomes of multicellular eukaryotes, class 1 elements usually make up the largest fraction of very large genomessuch as those from humans (~2500 Mb), maize (~2500Mb), and barley (~5000 Mb). Given what you knowabout class 1 and class 2 elements, what is it about theirdistinct mechanisms of transposition that would accountfor this consistent difference in abundance?Fig 3.16 EcoRI SacI KpnI |ampR Aval Xmal Smal lacZ BamHI Xbal SalI Accl HincII PstI Sphl HindIII Bam H1 Bam H1 Bam H1 1 2 3 4 The ends of the double-stranded DNA fragment above are blunt ends. The directionality of genes contained within the fragment is from left to right (arrow). After digestion by BamH1, which fragment can be inserted into the vector cut with BamH1 and Sma 1 maintaining the same directionality as the lacz promoter (green segment with arrow on vector)? 3 O 4 O1 2What is the basis for the lowfrequency of errors in DNA replicationobserved in all cells? Is this the bestthat cells can do given the speed ofreplication and the limits of moleculardiffusion? Was this mutation rateselected in evolution to provide geneticvariation?
- What Art the Features of the Series of -omes? Define the following terms: a. Genome b. Transcriptome c. Proteome d. Metabolome e. FluxomeIn addition to correcting DNA mismatches, themismatch repair system functions to prevent homologousrecombination from taking place between similar but notidentical sequences. Why would recombination betweensimilar, but nonidentical sequences pose a problem forhuman cells?If you compare the frequency of the sixteen pos-sible dinucleotide sequences in the E. coli and humangenomes, there are no striking differences except for onedinucleotide, 5ʹ-CG-3ʹ. The frequency of CG dinucleotidesin the human genome is significantly lower than in E. coliand significantly lower than expected by chance. Why doyou suppose that CG dinucleotides are underrepresentedin the human genome?
- The best estimate is that the human genome containsfewer than 21,000 genes. However, there is evidencethat human cells produce many more than 21,000 different polypeptides. What processes might account for thisdiscrepancy?Give two different reasons for the much higher ratioof total DNA to protein-encoding DNA in the humangenome as compared to bacterial genomes.Researchers who study the molecular mechanism of transformationhave identified many proteins in bacteria that function in theuptake of DNA from the environment and its recombination intothe host cell’s chromosome. This means that bacteria have evolvedmolecular mechanisms for the purpose of transformation by extracellularDNA. What advantage(s) does a bacterium derive from importing DNA from the environment and/or incorporating it into its chromosome?
- On further analysis of the DNA described in conceptual questionC21, you discover that the triplex DNA in this alien organism iscomposed of a double helix with a third strand wound within themajor groove (just like the DNA in Figure shown). How would youpropose that this DNA is able to replicate itself? In your answer,be specific about the base-pairing rules within the double helixand which part of the triplex DNA would be replicated first.What is meant by the term semiconservativereplication? What are the functions of DNA Pol I and III,helicase, and primase? How does a leading strand differfrom a lagging strand?The text stated that molecular biologists have developed elegant techniques that can convert any type ofDNA end into any other type of DNA end. In thisproblem, consider genomic DNA that is broken bymechanical shearing into random pieces. Some of theends of these pieces are blunt, some have 5′-overhangs, and others have 3′-overhangs.a. Must the two ends of any one genomic DNAfragment be of the same type?b. Explain why the ends with 5′ or 3′ overhangs arenot sticky.c. Researchers can convert ends with overhangs intoblunt ends using either DNA polymerase (plus thefour dNTPs), or nuclease S1, which degradessingle-stranded regions of DNA but not doublestranded regions. Which kinds of ends with overhangs (5′ or 3′) could be converted into blunt endsusing DNA polymerase? With S1 nuclease?
