An abnormal fruit fly has two sets of autosomes and is XXY.  Such a fly is

A pea plant has the genotype Rryy. Assume independent assortment. How many different types of gametes can it make and in what proportions?

A mechanism that can produce a translocation is 

A researcher conducted crosses between two different strains of Drosophila. When true-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) and vestigial wings (l), all F1 offspring had normal bristles and normal wings.  The F1 offspring were crossed to flies with singed bristles and vestigial wings. Which F2 offspring is/are recombinant?

In the lagging strand, DNA is made in the direction (                      ) the replication fork and is made as (                          ).

A DNA strand includes the following sequence: 5′-GATCCCCGATCCGAAATTTGACCTTTAA-3′ If this strand is used as a template by DNA polymerase, what would be the sequence of the newly made daughter strand?  In which direction would DNA polymerase slide along this strand (from left to right or from right to left)?  

The Mock Exam requires you to complete a Workspace Scan. Review the Workspace Scan – Test Taker Guide here. When you have finished doing so, select True. 

As part of the Mock Exam, you will need to verify your ID. Test the ID verification process here. When you have finished doing so, select True. 

You must show your work for this problem.  Place the setup and the calculation on paper (give the number of the question and show all your work) and enter the final answer here on Canvas.  When you are done the exam, take a picture of your work and upload it into the exam 3 work upload area. The answer you have here for the question(s) must match the work you provide in the upload area. (Keep in mind that in order to get full credit your must upload your work).   The pH titration  of 40.0mL of 0.411 M Bromoazirdine and 0.822 M hydrochloric acid is going to be run at the UNAC labs.  In order to test the validity of the titration you have been asked to predict the following five key points on the pH plot in order to test the equipment. (a). pH before the start of the titration (b). pH after the addition of 5.00 mL of HCl (c). pH at the half titration point (d) pH at the equivalence point (e) pH at 0.30mL after the equivalence

The first negative symptom of accidental ingestion of antifreeze is a [drop] in blood pH, while the secondary effect is [kidneystones].   A lake usually has carbonic acid, hydrogen carbonate and carbonate dissolved in the water these act as a [buffer], which allow the pH of the lake water to be stable. A acid/base titration is done in a lab, the point on the titration where the moles of acid actually equal the moles of base is termed the [EP], where by the assumed point of equal molar amounts is termed the [endpoint] and is based on an [indicator] changing color.
