In biology, a reading frame is a way of breaking a sequence of nucleotides in DNA or RNA into three letter codons which can be translated in amino acids. There are 3 possible reading frames in an mRNA strand: each reading frame corresponding to starting at a different alignment. 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.
