21. Studies have linked expression of CCDC113 in cancerous tissues to mutations present in the coding sequence . 22. Coding sequences were found to display a stylized pattern of 3-periodicity that non-coding sequences did not.23. If an editing site occurs within a coding sequence , it can result in a codon change. 24. Coding sequences were found to display a stylized pattern of 3-periodicity that non-coding sequences did not. 25. Two variants of the shorter transcript have been identified where alternative splicing affects the coding sequence . 26. Longer coding sequences are detected with higher probability. 27. Protein-coding sequences ( specifically, coding exons ) constitute less than 1.5 % of the human genome. 28. If an editing site occurs within a coding sequence , the result could be a codon change. 29. Each phone is assigned a code sequence that is approximately uncorrelated with the codes of other phones. 30. Usually alleles are coding sequences, but sometimes the term is used to refer to a non-coding sequence .
