Genetic engineers can design and assemble sophisticated gene circuits to program cells with new functions, but important signaling molecules can become diluted as these cells grow and divide, causing ...

When a gene is turned on in a cell, it creates a ripple effect along the DNA strand, changing the physical structure of the ...

Gene syntax alters DNA supercoiling to amplify or suppress nearby genes. This could improve the effectiveness of gene ...

A new type of synthetic biology circuit can be turned on within seconds, much faster than its counterparts. Credit: Massachusetts Institute of Technology Synthetic biology offers a way to engineer ...

Biological systems maintain homeostasis through feedback regulation, yet the quantitative principles that determine when such regulation remains effective are not fully understood. Our research ...

There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it takes for cells to behave in desired ways—for example, getting them to produce ...

The research team led by Professor Jongmin Kim from the Department of Life Sciences at POSTECH, along with graduate students Hyunseop Goh and Seungdo Choi, has successfully developed the 'Synthetic ...

Three characteristic features of natural biological systems are robustness, adaptability, and redundancy. Natural systems are remarkably resistant to failure induced by changes in component abundance ...
