Here is a sketch of a replication bubble of the parent strands, as you might see in E. coli. Arrows indicate the direction of the replication forks. DNA Replication Image Description A visual representation of DNA replication where G and F represent the DNA before it is split. A, D, C, and E show the split DNA to be paired with the new sequence along with the arrows that indicate the replication fork and B represents the 5′ end of the strand. If letter (b) represents the 5′ end of the strand it is nearest, where is (are) the most likely place(s) to see the Okazaki fragments? (Remember this would be with the NEW strands being made to base pair with the parent strands that are shown.)

This table records the percent of people with various blood types in a modern group of 228 members of the closed, conservative religious sect called Dunkers. This community was founded around 1720 in eastern Pennsylvania by 50 families who emigrated from the Rhineland region of Germany. Comparisons with contemporary German and US populations are included. Group # People Tested Type O Type A Type B Type AB Dunkers 228 35.5% 59.3% 3.1% 2.2% Rhineland Germans 3,036 40.7% 44.6% 10.0% 4.7% United States 30,000 45.2% 39.5% 11.2% 4.2% Pennsylvania 5,100 42.1% 44.2% 10.6% 3.1% What is the most likely explanation for these data?

How many gametes can be produced from an individual that is AaBbCcDd?

Should you accept or reject (fail to accept) the null hypothesis?

What is the doubling time (in years) for this population?

Which of the following is the source of new genetic variation in a population?

Use this illustration of a replication fork to answer the next five questions. Replication Fork Image Description Illustration of the replication fork. Enzyme X is on double-stranded DNS just before DNS unwinding. Enzyme Y is on structure N, which is replicated in the same direction as the replication fork. Structure M is on the other strand near the replication fork, and Point P is the place where two newly formed fragments are joining.

The somatic cells of a particular male organism contain only one pair of homologous chromosomes, call these chromosomes A1A2, and one additional chromosome without a homolog, call it chromosome Q. What chromosomal combination would be likely in the four meiotic products of a single cell?

A coon cat is brought to an island where only wild tabby cats live. After mating with other cats on the island, some of the kittens have bushy tails and tufted ears. What evolutionary mechanism is occurring?

The nontemplate strand of a DNA molecule has the sequence 5’TCTCGC3′. What is the sequence of the anticodon for the first amino acid in the sequence?
