Open reading frames An open reading frame(ORE)is a run of codons that starts with At and ends with a termination codon. TGA TAA or TAG Coding regions of genes contain relatively long OPFs unlike noncoding DNA where ORFs are 6/-. comparatively short
Open reading frames • An open reading frame (ORE) is a run of codons that starts with ATG and ends with a termination codon, TGA TAA or TAG. Coding regions of genes contain relatively long OPFs unlike noncoding DNA where ORFs are comparatively short
