General Characteristics for 100
Name this structure
What is Blastodisc?
Home
Cell Movements for 100
During the gastrula stage, this happens
around the whole embryonic margin.
What is involution?
Home
Signaling and Pathways for 100
The nodal signals are present in zebrafish.
What are squint and cyclops?
Home
Developmental Stages for 100
The Mid Blastula Transition (MBT) occurs
during this stage.
What is the Blastula stage?
Home
Experiments for 100
Zebrafish are a good model organism for
this genetic screen.
What is forward genetic screen
Home
General Characteristics for 200
The zebrafish egg shell.
What is the chorion?
Home
Cell Movements for 200
Cells that involute first and last give rise to
these structures.
What is anterior structures and posterior
structures respectively?
Home
Signaling and Pathways for 200
Where Nodal signal squint begin to be
expressed.
What is the Dorsal Yolk Syncytial Layer?
Home
Developmental Stages for 200
Zygotic transcription begins during this
stage.
What is the Blastula stage (MBT)?
Home
Experiments for 200
This protein allows cells to be visualized in
vivo.
What is Green Fluorescent Protein (GFP)?
Home
General Characteristics for 300
The Zebrafish embryo undergoes this kind
of cleavage.
What is Meroblastic Discoidal?
Home
Cell Movements for 300
The embryonic cells that undergo epiboly.
What are all cells? (not just ectoderm)
Home
Signaling and Pathways for 300
The Nieuwkoop needs these signals to
induce the organizer.
What are Beta-Catenin and Nodal?
Home
Developmental Stages for 300
When a fate map can be made.
What is Late Blastula? (after cell mixing)
Home
Experiments for 300
Transplanting a second organizer on the
ventral side causes this phenomenon.
What is double axis formation?
Home
General Characteristics for 400

Name this structure
What is Yolk Syncytial Layer?
Home
Cell Movements for 400
Involuting cells give rise to these germ
layer(s).
What are Mesoderm and Endoderm?
Home
Signaling and Pathways for 400
BMP is inhibited on the dorsal side by these
molecules.
What are chordin and noggin?
Home
Developmental Stages for 400
Epiboly begins in this stage.
What is the Blastula stage?
Home
Experiments for 400
This type of experiment occurs when Nodal
inhibitor Activin is added to the zebrafish
embryo there is a decrease in mesoderm.
What is loss of function?
Home
General Characteristics for 500
The yolk free area of a zebrafish embryo.
What is Blastodisc?
Home
Cell Movements for 500
Anterior-Posterior axis is formed by this cell
movement of this cell layer?
What are mesendoderm and ectoderm
undergoing convergent extension?
Home
Signaling and Pathways for 500
Notal signaling is required for this embryonic
layer formation.
What are Mesoderm and Endoderm?
Home
Developmental Stages for 500
Dorsal convergence to form the shield
occurs during this stage.
What is the Gastrula stage?
Home
Experiments for 500
A cyclops squint double mutation would
create this phenotype.
What is lack of mesoderm and endoderm?
