This figure shows the genetic composition of an individual for three genes. Which one of the following allele combinations is impossible in a gamete from this individual unless crossing-over occurs?

In tallgrass prairie ecosystems, bison are a keystone species. This means that ______. 

Type the correct letter or number corresponding to the answer options in the dropdown below. Molecule Name: [molecule] Enzyme or Reaction: [enzyme] Substrate or product of a reaction involving the molecule: [substrate] Image Description A complex molecule with a cobalt atom at its center. The cobalt atom is coordinated to four nitrogen atoms arranged in a square planar configuration, forming the corrin ring. This corrin ring consists of four pyrrole rings linked by methine bridges, forming a large macrocyclic structure. Attached to one side of the corrin ring is a nucleotide loop, which contains a ribose sugar, a phosphate group, and a nucleotide base. At the opposite side of the corrin ring, there is a dimethyl-benzimidazole group coordinated to the cobalt atom.  Answer Options Molecule Names Enzymes and Reactions Substrate or Product A.

In C. elegans, which is a small roundworm commonly used in genetics research, certain alleles of the gene “U” can lead to Uncoordinated movements by the worm. In addition, certain alleles of the gene “D” can lead to a worm that is shorter and wider than an average worm. The genes U and D are unlinked. If a UuDD worm is mated to a uuDd worm. What proportion of the offspring will be uuDD? 

The key advantage of the Cre/Lox system for targeted mutagenesis is that:

Which of these does NOT rely on molecules fitting together based on their compatible size, shape, and charge? 

Charlotte, a college student from State A, hit another car driven by Roberta, a resident from State B, when Charlotte was traveling through State B. Roberta brought an action in State B state court against Charlotte, who has limited financial resources. Charlotte filed a motion to dismiss, claiming the State B court lacks personal jurisdiction. What is the best argument to support Charlotte’s motion to dismiss?

Carly Casino Owner, a citizen of State A, sued Smith Construction, a corporation incorporated in State B with its principal place of business in that state, in a State B state court for breach of a contract to renovate her casino’s gaming floors. Carly claimed damages of $250,000. Smith Construction counterclaimed for $600,000, alleging that Carly breached an earlier contract by failing to pay for the remodeling of the hotel attached to the casino. Carly files a notice of removal to federal court in State B. Can the case properly be removed to the federal court in State B?

Type the correct letter or number corresponding to the answer options in the dropdown below. Molecule Name: [molecule] Enzyme or Reaction: [enzyme] Substrate or product of a reaction involving the molecule: [substrate] Image Description This molecule consists of a nitrogenous base connected to a ribose sugar. Attached to the opposite side of the ribose sugar as the nitrogenous base is a CH2 followed by three phosphate groups. The nitrogenous base is comprised of two fused rings, one a six-member ring and one a five-member ring. The six-member ring on the left consists of two nitrogens and four carbons. It is fused to the five-member ring via two of the carbons. The five-member ring on the right consists of two nitrogens and three carbons. On the six-member ring is a single amino substituent group attached to the top carbon.  Answer Options Molecule Names Enzymes and Reactions Substrate or Product A. PLP (Vitamin B6) L.

Info for Questions 1-6  You’ll answer the questions by typing the letter or number that corresponds to the correct answer. The table will also be in a dropdown for each question. We have studied a number of biochemical reactions associated with metabolism in the last half of the class. You will be asked to Identify these cofactors or coenzymes from the metabolic reactions we have encountered. Name a reaction or enzyme that requires the cofactor. Identify a possible product or reactant from any of the reactions in which the cofactor or coenzymes participate. Some answer options may be used more than once, and some answer options will not be used. Some questions have more than one acceptable answer that will receive credit; you only need to select one example that is correct. You can, but do not necessarily, need to match your enzyme name found in column 2 with the product and or reaction in column 3. You can mix and match. (i.e., You can only pick one answer even if there is more than one that would be correct.) You will receive credit for any correct answer. Molecule Names Enzymes and Reactions Substrate or Product A.
