Find the slope of the line that goes through the given points: (7, 8), (6, -4)

,.  A portion of the non-coding (“sense”) strand for a given gene has the sequence 5′-ACTGTCGCACAG-3′ Blank #1: How many hydrogen bonds can be established between the nitrogenous bases in the portion of the non-coding strand above and the nitrogenous bases in the complementary, coding strand?  Blank #2: What is the sequence of the complementary (coding) strand in DNA? Identify the 3′ and 5′ ends.  Blank #3: What is the sequence of the mRNA that would be produced during transcription from the coding strand? Identify the 3′ and 5′ ends.  Blank #4: What amino acid sequence does this code for?  Blank #5: The aminoacyl t-RNA synthase that catalyzes the condensation of methionine to the acceptor stem of a given t-RNA would recognize which anticodon in the t-RNA?

A hexapeptide that is part of a mouse hormone was hydrolyzed to give the following amino acids (in no particular order): Tyr (Y), Cys (C), Glu (E), Ile (I), Lys (K), Met (M).  a) two cycles of Edman degradation of the intact hexapeptide releases the PTH-amino acids below. Remember that the Edman reagent reacts with the N-terminus amino acid and cleaves it off as a cyclic structure (PTH), where only the R group of the amino acid is recognizable. b) cleaving the intact hexapeptide with cyanogen bromide yields Met and a pentapeptide c) treating the intact hexapeptide with trypsin yields a dipeptide, which contains Tyr and Glu, and a tetrapeptide d) when the intact hexapeptide is treated with carboxypeptidase A, a Tyr residue and a pentapeptide are produced.  Write the sequence of the hexapeptide in the blank below. 

Given the following values for the distances travelled and times, report the average terminal velocity for your droplets. Droplet Distance (mm) Time (s) Volt (V) 1 0.375 19.30 18.8 2 0.375 4.11 29.1 3 0.500 3.54 30.4  where … vt = terminal velocity d = distance (in m) t = time (in s)

What is the net ionic equation for the reaction between Fe3+(aq) and Na2S(aq)?

Applying a voltage of 8.00 V, moves the beam 3.00 cm (in the direction an electric field moves the beam). If it requires a magnetic field of 27.0 mT, to balance an electric field of 8.00 V, use the equation below to determine the charge-to-mass ratio.

Using the picture of the detector locations, which of the following charts would you expect to be produced from the Rutherford experiment for the number of alpha particle hits.  

If you obtained the following values for the charge of an electron, find the average charge on one electron and use that value to determine the mass of the electron. Droplet Calculated charge on one electron 1 1.591 × 10-19 C 2 1.445 × 10-19 C 3 1.652 × 10-19 C  

In which direction does the application of an electric field move the beam in the Thomson Cathode Ray experiment?
