The reaction A + B -> C has a DG'° of –20 kJ/mol at 25° C.  Starting under standard conditions, one can predict that:

#SCPH01 Biochemistry
  1. at equilibrium, the concentration of B will exceed the concentration of A.

  2. at equilibrium, the concentration of C will be less than the concentration of A.

  3. at equilibrium, the concentration of C will be much greater than the concentration of A or B.

  4. C will rapidly break down to A + B.

You are practicing designing primers that you can use in PCR reactions. You want your primers to allow you to amplify the sequence found below.
 

 
(a) 5’-ACTTCGATATGTCTAAAATAC-3’ and 5’- CGGTAGCGTCTCTGGTTAGCT -3’
(b) 5’-TGAAGCTATACAGATTTTATG-3’ and 5’-GCCATCGCAGAGACCAATCGA-3’
(c) 5’-GTATTTTAGACATATCGAAGT -3’ and 5’-AGCTAACCAGAGACGCTACCG-3’
You are asked to design a 15-nucleotide-long primer that could potentially hybridize to a portion of a specific mRNA that encodes the protein sequence N-Met-Ala-Tyr-Trp-Pro-C. How many different primers would you have to design in order to ensure that one of them will in fact hybridize along its full length to the mRNA?

You are a scientist who is using genomics to currently study a new bacterial species that no one has ever studied before. The following sequence is a piece of DNA within the coding region of a gene that you have recently sequenced.
 
If you take any bacterial gene sequence, before you begin doing any sequence analysis on it, there are six potential open reading frames. Why are there six?
