A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
In all living organisms, proliferating cells go through the fundamental process of DNA replication. Through this process, they faithfully duplicate their DNA and divide into two daughter cells. In ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
When TV shows like CSI: Crime Scene Investigation portray DNA processing in the forensic lab, the results appear instantly with a DNA match wrapping up the case in hours. However, the ...
A common hallmark of viral genome replication is a high mutation rate, which can aid in their ability to evade new treatments and acquire resistance to once-effective antiviral medications. Now, a new ...
Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA and RNA. PCR involves the enzymatic amplification of ...
Researchers identified how the poxvirus protein VITF-3 forms a molecular ring that clamps onto DNA with viral RNA polymerase, bending it by 90 degrees to initiate gene copying.
