Exam 8: Dna Replication, mitosis and the Cell Cycle

People with xeroderma pigmentosum (XP)are at greater risk of skin cancer because:

In an asexual life cycle,cells reproduce by:

Cyclophosphamide forms crosslinks between the two strands of DNA in a chromosome.How would this be effective in chemotherapy?

The chemotherapy drug taxol inhibits microtubule function.A cell treated with taxol would become stuck in which phase?

Why don't plant cells form a cleavage furrow during cytokinesis?

The pair of unmatched chromosomes in humans:

figure 8.26 -What did the researchers conclude from figure 8.26a?

The portion of the cytoskeleton that enables the chromosomes to be separated equally into two sets is the:

The enzyme telomerase adds DNA to the ends of chromosomes.Why would cancer cells express high levels of telomerase?

The reason that the type "S" bacteria could infect mice and cause pneumonia was because:

The process used to determine the order of bases in DNA is DNA sequencing.

In humans,specialized cells that produce gametes are:

Stem cells from an adult

The process by which DNA reproduces itself is:

The process used to rapidly produce DNA sequences of interest is DNA sequencing.

When DNA replicates:

The enzyme that unwinds DNA is:

For the polymerase chain reaction (PCR)to work,the Taq _______ must be heat stable to avoid denaturation.

The four nitrogen bases that are found in the different nucleotides of DNA are:

The enzyme that joins Okazaki fragments is:
