(Phys.org)—Synthetic biology is a multi-disciplinary field that applies engineering techniques to biological systems. While the foundations of synthetic biology were laid in the 1990s with the burgeoning of genomics and ...
The DNA in our cells is folded into millions of small packets, like beads on a string, allowing our two-meter linear DNA genomes to fit into a nucleus of only about 0.01 mm in diameter. However, these molecular beads, called ...
