Image of DNA helix model (closeup).

Image of DNA helix model (closeup). By this point, most scientists believed that DNA carried hereditary information. So having solved the structure, Watson and Crick's comment was a teaser, in reference to two fairly obvious questions. If DNA is in the shape of a twisted ladder, then:

how is the information stored in the DNA molecule passed on to the next generation?

how is the information stored in the DNA molecule used to make protein?
