Consider the 2-D wedge-shaped vehicle shown. The vehicle has a mass of 9000 kg, and its engine (not shown) provides 70 kN of thrust. The vehicle is in level (constant-altitude) flight. The sides’ lengths, angles, as well as the averaged (uniform) pressures and shear stress magnitudes on the different surfaces are tabulated below. Neglect friction on the leeward side (face ).   = 7.732 m

The straight portion of the fallopian tube that connects the intramural and ampullary portion is?

How can I improve this class?

Transfer of genetic material from one bacterium to another can occur in three ways: Conjugation: Involves direct physical contact Transduction: Involves bacteriophages Transformation: Involves uptake from the environment

There are 3 common ways to modulate the function of regulatory transcription factors. The figures that represent them are below. Briefly explain each.  1)  2) 3)

In order to characterize the entire promoter for gene X, researchers cloned three regions of DNA that based upon their position and sequence could serve as a core promoter, a proximal promoter, or an enhancer element.  They subcloned each these regions into luciferase reporter constructs as described and depicted below. Construct A represents the luciferase vector without any promoter elements. Construct B represents the element in its normal position and orientation.  Construct C represents the element in its normal position, but in the reverse orientation. Construct D represents the element in a different position, but its normal orientation. Construct E represents the element in a different position AND in the reverse orientation.  The results below are for one of the three elements tested.  The darker color represents samples that had luciferase activity. Assuming all the control and additional requirements for transcription are correct and met, the test below represents [element] because it is position [reason1] and orientation [reason2].     .

What is the CRISPR-Cas system? How did scientists use it to make an exceptional genetic engineering tool?

What is the mechanism of RNA interference?   Hint words: pri-miRNA, Drosha-DGCR8 complex, pre-miRNA, dicer, RISC complex, target mRNA, Argonaute.

Gene mutations outside of coding sequences can affect gene expression and phenotype. Mutations in the core promoter can change levels of gene transcription.
