Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA ...

Swirling inside every cell are millions of microscopic messages called messenger RNAs (mRNAs). The messages are the genetic ...

Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

duplex unwinding and protein displacement by these enzymes and especially how these activities are regulated by accessory proteins. Helicases and nucleic acid translocases are motor proteins that ...

Using cutting-edge cryo-electron microscopy, scientists at the University of Leicester have captured the first detailed ...

Using cutting edge cryo-electron microscopy, the team of scientists were able to visualise a helicase enzyme (nature's DNA unzipping machine) in the process of unwinding DNA. DNA helicases are ...

Using cryo-electron microscopy and deep learning to observe the helicase Simian Virus 40 Large Tumor Antigen interacting with DNA, the laboratories of KAUST Assistant Professor Alfredo De Biasio ...

RNA helicase, RNA, and single-stranded DNA to form a nuclear protein complex which may be involved in transcriptional events as a member of an mRNA factory. Discovery of a novel O-glycosylation of ...

This process of protein synthesis occurs in two stages ... This unwinding of the helix is caused by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding ...
