Francis Crick

I also suspect that many workers in this field [of molecular biology] and related fields have been seriously misled by the recency of the theoretical basis for molecular biology.

The genetic code is nearly universal, suggesting that all life on Earth has a common ancestor.

Biology is becoming too difficult for biologists to understand.

The attempt to find an adequate and meaningful definition of life has been a central problem for biologists.

Science is fundamentally a communal effort.

It seems likely that the genetic code is not only universal but also unambiguous.

The structure of DNA suggested a mechanism for its replication.

Personal life is a matter of taste, but professional life is a matter of principle.

The origin of life appears at the moment to be almost a routine extension of molecular biology.

We are sometimes asked 'What is the aim of this work?' We do not think there is any.

If you want to understand function, study structure.

The code is read in groups of three bases, each group specifying an amino acid.

Chance favors the prepared mind.

Molecular biology is the study of biology by means of molecules.

The most significant development in molecular biology was the discovery of the double helix.

Life is a self-replicating system.

It is hard to imagine a more satisfactory result than that obtained by Watson and Crick.

The transfer of information from DNA to RNA to protein is the central dogma of molecular biology.

I went into science because of three things above all: my curiosity, my impatience with the world as it was, and my hope of making it better.

The secret of life is to be found in the nucleus.
