Biology’s four-letter DNA alphabet just expanded to eight
An essential cellular enzyme successfully transcribed synthetic DNA letters, bringing expanded genetic codes closer to biological use.
Two new federally funded studies offer detailed views of proteins repairing broken DNA inside tightly packed chromatin, and of the molecular toolkit they assemble at a break, with potential implicatio ...
Every cell in the human body contains about 2 meters of DNA, roughly the length of a bed. Though too small to see with the naked eye, DNA is intricately organized, allowing it to govern cellular ...
The shape and morphology of a cell play a key role in the biological function. This corresponds to the principle of "form follows function," which is common in modern fields of design and architecture ...
