The nucleus of a mouse embryo at the two-cell stage (IMAGE)
Caption
On the left, an image of a mouse embryo at the two-cell stage with its two nuclei visible in green. On the right, a 3D rendering of a single nucleus in a two-cell-stage embryo. The nuclear surface (blue) is noticeably deformed. This allows the genes with active transcription necessary for further embryonic development (green) to get close to polymerase and be transcribed into RNA (red) and then translated into proteins.
