Q: What is a processive enzyme? Explain why processivity is an important
What is a processive enzyme? Explain why processivity is an important feature of DNA polymerase.
See AnswerQ: What enzymatic features of DNA polymerase prevent it from replicating one of
What 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...
See AnswerQ: As shown in Figure 11.24, telomerase attaches additional DNA
As shown in Figure 11.24, telomerase attaches additional DNA, six nucleotides at a time, to the ends of eukaryotic chromosomes. However, it makes only one DNA strand. Describe how the opposite strand...
See AnswerQ: If a eukaryotic chromosome has 25 origins of replication, how many
If a eukaryotic chromosome has 25 origins of replication, how many replication forks does it have at the beginning of DNA replication?

With regard to the T and t alleles, explain what the word segregation means.
See AnswerQ: A diagram of a linear chromosome is shown here. The end
A diagram of a linear chromosome is shown here. The end of each strand is labeled with A, B, C, or D. Which ends could not be replicated by DNA polymerase? Why not? 5′–A———————————————————B–3′ 3′–C——...
See AnswerQ: As discussed in Chapter 18, some viruses contain RNA as their
As discussed in Chapter 18, some viruses contain RNA as their genetic material. Certain RNA viruses can exist as a provirus in which the viral genetic material has been inserted into the chromosomal D...
See AnswerQ: Telomeres contain a 3′ overhang region, as shown in Figure
Telomeres contain a 3′ overhang region, as shown in Figure 11.22. Does telomerase require a 3′ overhang to replicate the telomere region? Explain. From Figure 11.2...
See AnswerQ: The base composition of an RNA virus was analyzed and found to
The base composition of an RNA virus was analyzed and found to be 14.1% A, 14.0% U, 36.2% G, and 35.7% C. Would you conclude that the viral genetic material is single-stranded RNA or double-stranded R...
