"How Cells Count and Measure"

Although genomic and proteomic methods are rapidly
revealing the complete molecular "parts list" of the
cell, the question remains of how these parts are
arranged into defined cellular stuctures is still
mysterious. What determines the size of cellular
sub-structures? What determines how many copies of
each structure a cell contains? The ability of cells
to regulate the size and copy number of their
sub-structures (organelles) suggests that cells may
posess mechanisms for counting and measuring. We are
attempting to understand these mechanisms by studying
two model systems - length control of eukaryotic
flagella, and copy number control during centriole inheritance.
