Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely ...

Four graphs show the patterns of gene expression at 4 time points during early drosophila embryo development. The spatial distributions of gene expression are represented in line plots for each ...

The ZINC's primary activities would be to microinject RNA and DNA oligonucleotides or interference RNA into zebrafish embryos. The IACUC questioned how ZINC would handle certain situations ...

METHODS: That biological system is the Drosophila embryo, introduced to Gregor by another of his PhD advisors at Princeton, Eric Wieschaus, a developmental biologist. Gregor recognized that the ...

Scientists found that fruit fly embryos can develop through multiple genetic paths, not just one. This challenges traditional ideas.
