With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's.

The first resource containing high-resolution DNA sequencing data for over 37,000 children and parents collected over multiple decades from across the UK is now available to researchers worldwide.

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves.

Comparison of several high resolution complexes of DNA polymerases bound with relevant substrates indicates that the two major families of polymerases function by very similar mechanisms.
