Inside a replicated chromosome

A simplified structural zoom from a condensed replicated chromosome through chromatin and DNA wrapped around histone proteins, into a double helix, complementary bases and selected genetic marker positions.

Use the journey slider or stage buttons to explore. Drag the chromosome and molecular views, or use the left and right arrow keys, to rotate them.

A condensed chromosome has two sister chromatids. Each contains one double-stranded DNA molecule.
