#Unit 6. System Physiology – Plant

PIN1 mediates vertical transport of IAA from the shoot to the root along the embryonic apical–basal axis and creates an auxin sink that drives basipetal auxin transport upward from the root apex via PIN2 efflux carriers.

#Unit 2. Cellular Organization

The DNA-binding domain occupies residues 1–59. It contains two a-helices separated by a turn. This is a common DNA-binding motif known as the HTH (helix-turn-helix); the two a-helices fit into the major groove of DNA

#Unit 11. Evolution and Behavior

When a nonfunctioning duplicate is fixed in the population, or a functioning gene becomes nonfunctional, the result is a genetic skeleton called a pseudogene.

Deletions are important in shaping the genome.
