Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three ... whereas most eukaryotes have one or more linear chromosomes, which ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

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

DNA is a linear biopolymer, a compound biomolecule ... (chromosomes that don't code for sex-linked traits). In its structure, DNA contains a pattern for producing amino acids, proteins, lipids ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

Each cell in our body contains a copy of our DNA code made up of A, C, G and T, providing the blueprint for the organization and function of our bodies. Normally these letters combine in pairs to form ...
