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?

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. There are 3 reading frames on each of two strands, because the top strand looked like the mRNA, then the reading frame could start with a CCC, a CCG, or a CGT and If the bottom strand looked like the mRNA, then the reading frame could start with a TGT, a GTT, or a TTC.
  2. There are 6 reading frames on each of two strands because the strand look like the mRNA, then the reading frame could start with a CCC, a CCG, a CGT, a GTA, TAC or a ACG.
  3. There are 3 reading frame only on the top of the strand looked like the mRNA, then the reading frame could start with a CCC, a CCG, or a CGT.
  4. There are 3 reading frames on each of two strands, because the top strand looked like the mRNA, then the reading frame could start with a CCC, a CCG, or a CGT and If the bottom strand looked like the mRNA, then the reading frame could start with a GGG, a GGC, or a GCA.

Acetobacter aceti converts alcohol to acetic acid according to the stoichiometric  relation 
 C2H5OH + O2   →       CH3COOH + H2O 
In a vigorously agitated and aerated reactor containing 20 g/l ethanol, the organism  produces 16 g/l acetic acid and 2 g/l was the residual ethanol concentration. What are the  theoretical and observed yields of acetic acid expressed in g/g ethanol?
