Asymmetric movements of cytoplasmic components in <i>Caenorhabditis elegans</i> zygotes

Name: Work Video:
Duration: 3 min 30 s
Description: One of the central problems facing developmental biologists is understanding how the unicellular zygote develops into a multicellular embryo composed of different tissue types. It is now clear that differentiated cell types differ because they express different sets of genes. However, how cells become instructed to express different sets of genes remains a mystery.
