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?

  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.
