discovery of the sugar-phosphate backbone of the DNA molecule was still years away. The large number of molecular groups made available for binding by each nucleotide component meant that there ...

sugars, and every other biomolecule an organism makes. The parts of a DNA molecule that have these instructions are called genes. An individual's genome is the sum total of their genes.

In short, DNA is a complex molecule that consists of many components ... from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs.

Punishing conditions in the clouds of Venus could be home to a DNA-like molecule capable of forming genes in life very ...

For a long time, Venus has been considered too hostile for life as we know it. Its thick clouds are filled with droplets of ...

In 1952, Alfred Hershey of Cold Spring Harbor Laboratory and his lab technician, Martha Chase, wanted to confirm that DNA was the carrier of genetic information. They tagged the protein coating of ...
