Talk:Reading frame

Vague statement

"Double stranded DNA has six different reading frames molecule due to the two strands from which transcription is possible - three of them reading forward and three of them reading backwards." Is it correct to interpret this statement as saying: double stranded dna consists of 2 strands with opposite alignment (3' 5' direction is reversed, and reading frame may be on either side, but is always read in the same 3' to 5' or was it opposite direction)? otherwise I see 2(strands)*3(nucleotides)*2directions=12 reading frames...
