Explore Drosophila development and embryonic protein distribution.
Eric Wieschaus and Christiane Nüsslein-Volhard explain research of Drosophila's developmental stages, and Ed Lewis presents homeotic mutations.
Figure from Sargent and Dawid's differential expression experiment in frog embryos.
This method uses homologous recombination to disable a gene of interest to produce a genetic knockout.
Erwin Chargaff talks about his name for Chargaff's ratios.
A cuticular preparation of a wild-type Drosophila embryo highlighting the segments and body structure.
Different gene combinations result in different dominant/recessive ratios in offspring.
Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure.
Dr. Sumner describes family planning options for parents who have a child with SMA.
Fruit fly mutaitons provided keys to understanding the molecular basis of large-scale developmental plans.
