Textbook Question
Chapter 7, Problem 23P
Why do the genomes of eukaryotes, such as Drosophila, need to have multiple origins of replication, whereas bacterial genomes, such as that of E. coli, have only a single origin?

- A large portion of the human genome is transposons. Collectively, they are most likely: A) an equal mix of DNA and retrotransposons B) mostly DNA transposons because they are found in DNA C) mostly retrotransposons because they copy themselves each time they move D) mostly DNA transposons because they can cut themselves outarrow_forwardIn bacteriophages and bacteria, the DNA is almost always organized into circular (closed loops) chromosomes. Phage l is an exception, maintaining its DNA in a linear chromosome within the viral particle. However, as soon as this DNA is injected into a host cell, it circularizes before replication begins. What advantage exists in replicating circular DNA molecules compared to linear molecules, characteristic of eukaryotic chromosomes?arrow_forwardWhat are some of the ways that organisms use to ensure the fidelity of DNA replication? Why is it important that the fidelity of DNA replication is an evolutionary balance between faithful replication and the existence of some errors? Escherichia coli and other bacteria methylate adenines on the original strand to distinguish the original strand from the newly replicated strand of DNA. Why is this distinction important?arrow_forward
- Why do eukaryotes need multiple origins of replication?arrow_forwardWhat enzymatic features of DNA polymerase prevent it from replicating one of the DNA strands at the ends of linear chromosomes? Compared with DNA polymerase, how is telomerase different in its ability to synthesize a DNA strand? What does telomerase use as its template for the synthesis of a DNA strand? How does the use of this template result in a telomere sequence that is tandemly repetitive?arrow_forwardIs eukaryotic replication bidirectional or unidirectional?arrow_forward

- Why are some eukaryotic genomes so large?arrow_forwardWhat Is The Origin Of Replication? How many are found in prokaryotes and how many are found in eukaryotes?arrow_forwardDuring the process of transcription, the polymerase must handle several distinct polynucleotide chains: the double-stranded DNA ahead of the polymerase, the single-stranded template DNA, the nontemplate DNA strand, and the freshly-synthesized mRNA. How does the polymerase keep each of these strands--as well as the incoming ribonucleotides needed for the polymerase reaction--separate?arrow_forward
