The Label as DNA, Label as RNA and Label as Protein tools, located in the Functions section of the Toolkit panel, mark the sequences in a set as being DNA, RNA, or protein. This ability may be useful for sequences originating in formats where type is unspecified, such as FASTA files.

If you use any of these functions, the information will be added to the output file, where allowed (e.g., .gbk). The presence of sequence type information may affect the results of searching in an endpoint expression. For example, in DNA, “N” = anything, whereas in protein, “N” = asparagine.
