11. Arrayed along the ring of DNA are the coding sequences for 1, 590 genes. 12. However, many stop codons appear off-frame within coding sequences , termed " hidden stops ". 13. The OPN gene is composed of 7 exons, 6 of which containing coding sequence . 14. The coding sequence is from base pairs 151 to 624. 15. Alternatively, the code sequence may indicate that Test & Set Queuing is being used. 16. Protein-coding sequences represent the most widely studied and best understood component of the human genome. 17. Current estimates are that the DNA contains the coding sequences for some 70, 000 genes. 18. The 3'coding sequence of this gene contains a polymoprhic region of 24 nt tandem repeats. 19. The positions of exons within the coding sequence can be used to infer common ancestry. 20. Using these sixteen unique codes, 64 different code sequences are transmitted which serve two purposes.
