 __DNA id__: id number for the whole DNA sequence, sequences with same DNA id are from same DNA  
 __Organism__: Organism of the DNA  
 __year__: the year of the DNA sequence       
-__region type__: determine the general type of the sequence, such as coding, regulator, repeat region, etc.(__Note__: when classifying coding type, all the CDS, mRNA, tmRNA, tRNA,rRNA and others such as propetide, sig_propetide,mat_propetide was classified as coding. In order to minimize the missing coding part, all the other categories which has associated product was also classified as coding )   
+__region type__: determine the general type of the sequence. For all the type that is typically classified as coding region, it was named with coding; while others including those that are case dependent were named according to their own type such as regulator, repeat_region,gap, intron,extron, etc.(__Note__: when classifying coding type, all the CDS, mRNA, tmRNA, tRNA,rRNA and others such as propetide, sig_propetide,mat_propetide was classified as coding. In order to minimize the missing coding part, all the other categories which has associated product was also classified as coding )   
 __specific class__: if the sequence is coding sequence, it would be classified according to their production type such as RNA, Protein. The regulators would also be classified by their own class such as terminator, ribosome  
-__Product__ : if the sequence produce protein, the product name would be listed
+__Product__ : if the sequence produce protein, the product name would be listed  
 __sequence__: the actual sequence   
 __gc_content__: the gc_content of the sequence  
 __translation code__: if the sequence produce protein, then the translation code would be provided as a reference  
-__start_position__: the start position of the segment
+__start_position__: the start position of the segment  
 __end_position__: the end position of the segment
