When eukaryotic DNA undergoes replication, DNA helicase opens many sites along the DNA molecule at which DNA replication initiates. These sites are called "origins of replication." In what way does having multiple sites of replication affect the process of DNA replication?
A) It makes the process occur more quickly.
B) It allows longer molecules to be generated.
C) It ensures that errors in DNA replication never occur.
D) It allows proteins to be generated at the same time as DNA.
Ans: A) It makes the process occur more quickly.

Turtle hatchling survivorship rate is low in many turtle species due to predation. Amanda researched the predatory rate on a species of turtle eggs in the Red River. The eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. Research suggests that predators use the female's cloaca scent to locate the eggs.The eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. The nests were monitored by cameras and manually on foot and data on nest predation were recorded.Based on the experimental design, what is the dependent variable?
A. Time eggs spent in ground B. Number of hatchlings C. Eggs without cloaca film D. Cloaca film on eggs

Why does an embryo with a balanced translocation have the same chance for normal development that an embryo with a normal karyotype has?
A. The translocation stimulates DNA repair mechanisms to correct the problem before commitment occurs. B. The embryo's somatic cells are unaffected, expressing a normal karyotype; only germline cells express the translocation. C. Although the location of the genetic material is abnormal with a balanced translocation, there are no missing or extra alleles. D. When a zygote with a balanced translocation reaches the embryo stage without a spontaneous abortion, the risk for abnormal development decreases.
