UC San Diego structures show E. coli RNA polymerase reads four synthetic DNA letters the same way it reads the natural four.
Every time a cell divides, it must copy roughly three billion letters of DNA with near-perfect fidelity. That copying process, DNA replication, is among the most demanding operations a cell performs, ...

Scientists have identified a previously unrecognized layer of the human genome. It's built not from DNA's usual building blocks, but from small fragments of RNA embedded directly inside it. Georgia ...
By simulating a billion years of Earth’s history, researchers have identified a possible window for life’s earliest chemistry ...
A soybean enzyme better known for its role in plant hormone chemistry has been unmasked as an unexpected accomplice of a ...

Life uses four DNA letters, but scientists made an eight-letter system work
Every known organism writes genetic information with four DNA letters, but laboratory chemistry is not limited to that ...
A new study suggests that RNA can become dangerous when cells accumulate more of it than they can clear. Credit: Stock. A virus may cripple a cell’s power supply simply by produ ...
早已死透的细菌，竟然能把活着的同类拖下了地狱。这是科学界一场著名的借尸还魂。离奇夺舍英国医生格里菲斯手里有两种肺炎菌：致病的强毒菌，和无害的弱毒菌。格里菲斯按照实验步骤将加热杀死的致病强毒菌与活着，但人畜无害的弱毒菌混在一起，注入小鼠体内。不久，小鼠突然离奇暴毙！更诡异的是，格里菲斯从小鼠尸体里掏出 ...
RNA library preparation begins with an unavoidable problem: ribosomal RNA (rRNA) accounts for approximately 80% or more of total cellular RNA in most eukaryotes, leaving little sequencing capacity for ...
