EEB 184 Exam 1 Questions And Answers
(Guaranteed A+)
Housekeeping genes - answer✔encode proteins with roles in essential processes in all cells of
the body
Toolkit genes - answer✔encode proteins with roles in the formation and patterning of body
plan and body parts; act directly/indirectly to control expression of other genes; widely
conserved among animal phyla
Pax6 - answer✔codes for eye development
Gap genes - answer✔influence development of segments; mutations can lead to loss of large
portions of embryo
Transcription factors - answer✔regulate the expression of other genes during development
Pair-rule genes - answer✔define edges of individual sections
Ernst Mayr - answer✔did not think that development was needed to explain evolution
Huxley - answer✔evolution takes place by epigenesis(body construction); "Arrival of the Fittest"
; coined Modern Synthesis
Pleiotropy - answer✔one gene influences two or more phenotypic traits
Darwin - answer✔descent with modification; new adaptations are modifications of old parts
Genetic drift - answer✔random build up of mutations cause them to drift into 2 different
populations
Morphogenesis - answer✔generation of the shape of an organism by embryological processes
of differentiation of cells, tissues, and organs and the development of organ systems
Cis-regulatory element - answer✔acts on individual genes to allow independent spatial and
temporal control of discrete features of gene expression and function
Histone acetylation - answer✔loosens nucleosomes and allows transcription
Maternal effect genes - answer✔genes coming from the mother that affect formation
