Sequence, complementary
Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.

- Sequence, conserved
A base sequence in a DNA molecule (or an amino acid sequence in a protein) that has remained essentially unchanged throughout evolution.
- Sequence, draft DNA
Sequence of a DNA with less accuracy than a finished sequence. In a draft sequence, some segments are missing or are in the wrong order or are oriented incorrectly. A draft sequence is as opposed to a finished DNA sequence.
- Sequence, finished DNA
A DNA sequence in which the bases are identified to an accuracy of no more than 1 error in 10,000 and are placed in the right order and orientation along a chromosome with almost no gaps. A finished sequence is as opposed to a draft DNA sequence.
- Sequence, intervening
An intervening sequence is the part of a gene that is initially transcribed from the DNA into RNA (specifically, into the primary RNA transcript) but then is excised (removed) from it when the so-called exxon sequences on either side of it are spliced together. Intervening sequences intervene between the exxons. Intervening sequences are also called […]
- Sequence, regulatory
A sequence of bases in DNA that controls gene expression.
