。 If a feature is located on the complementary strand, the word "complement" will appear before the base span. 3 、 5< ： 5 ’。 If the "<" symbol precedes a base span, the sequence is partial on the 5' end (e.g., CDS <1..206). If the ">" symbol follows a base span, the sequence is partial on the 3' end (e.g., CDS 435..915>. 4 、 /db_xref ：。

might be read as:
The feature CDS is a coding sequence beginning at base 23 and ending at base 400, has a product called 'alcohol dehydrogenase' and is coded for by a gene called“ adhI ” A more complex description:

====/product="T-cell receptor beta-chain"
which might be read as:
This feature, which is a partial coding sequence is formed by joining elements indicated to form one contiguous sequence encoding a product called T-cell receptor beta-chain.
