Positive and Negative Selectable Markers
- Positive selectable markers are selectable markers that confers selective advantage to its host organism. An example would be antibiotics resistance, which allows the host organism to survive antibiotics selection.
- Negative selectable markers are selectable markers that would eliminate its host organism upon selection. An example would be thymidine kinase, which would make the host sensitive to ganciclovir selection.

Famous quotes containing the words positive and/or negative:
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
“There is no reason why parents who work hard at a job to support a family, who nurture children during the hours at home, and who have searched for and selected the best [daycare] arrangement possible for their children need to feel anxious and guilty. It almost seems as if our culture wants parents to experience these negative feelings.”
—Gwen Morgan (20th century)
