The development of animal embryos is initially directed by maternal gene products. Then,
during the maternal-to-zygotic transition (MZT), developmental control is handed to the …

Morphogen gradients provide concentration-dependent positional information along polarity
axes. Although the dynamics of the establishment of these gradients is well described …

For over 40 years, the Bicoid-hunchback (Bcd-hb) system in the fruit fly embryo has been
used as a model to study how positional information in morphogen concentration gradients …

Transcription factors play an essential role in pattern formation during early embryo
development, generating a strikingly fast and precise transcriptional response that results in …

This is a comprehensive guide to single-stranded RNA phages (family Leviviridae), first
discovered in 1961. These phages played a unique role in early studies of molecular …

Quantitative cell biology requires precise and accurate concentration measurements,
resolved both in space and time. Fluorescence correlation spectroscopy (FCS) has been …

During development, cell identity is established reproducibly among individuals through the
expression of specific genes at the correct time and correct location in space. How genes …
