Biochemists have developed a new strategy for controlling the biological functions of DNA (deoxyribonucleic acid) by means of light and therefore provide a tool to investigate processes which take ...

Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...

Neurons are the anatomical and functional unit of the nervous system, regulating both vital functions and higher functions. Among the very few cells in the body that do not regenerate, these cells ...

Fluorogenic DNA aptamers produce light only in the correct structural state, enabling programmable molecular logic, biosensing, DNA origami integrity reporting, and reusable mRNA detection through ...

DNA nanotechnology involves the development of synthetic DNA genomes. Owing to their unique chemical and structural properties, DNA is used as programmable material for the controlled synthesis of ...

Just as countries import a vast array of consumer goods across national borders, so living cells are engaged in a lively import-export business. Their ports of entry are sophisticated transport ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...
