December: 9 MSc thesis defences at CCMAR

Between the 6^th and 18^th of December 9 students of the Master in Marine Biology will defend their thesis.

Our researchers wanted to understand how the growth of bivalve shells is regulated. They identified long noncoding RNAs, as candidate biomineralisation-related genes involved in shell growth and maintenance.
