# Shriram Coli

What if an *E. coli* cell was the size of the Shriram building at Stanford? If 1 µm = 100 m, we calculate the size of a few biological objects.

## Sizes

Object | Size |
---|---|

Bp | 3.4 cm |

H2O | 2.75 cm |

GFP | 30 cm |

Ribosome | 200 cm |

bilayer | 40 cm |

T7 | 580 cm |

mRNA | ~30 m |

Genome | 158 km |

## Rates

At the same size scale, we can calculate how fast various cellular components would be moving:

Process | Rate (m/s) |
---|---|

RNAP | 1.7 |

DNAP | 3.4 |
