Free DNA nucleotides – needed to form the new strands. DNA polymerase – an enzyme that adds new nucleotides to a growing strand of DNA. Primers – A primer is a short strand of nucleotides th ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... for the synthesis of a new complementary strand. DNA ...

Scientists have yet to identify a polymerase that can add bases to ... The study of DNA replication started almost as soon as the structure of DNA was elucidated, and it continues to this day.

An RNA polymerase II molecule is about 15 nanometers across, or roughly 5,000 times smaller than the width of a human hair. This image was created by reconstructing X-ray diffraction crystallography ...

Now, researchers used cryoelectron microscopy (cryo-EM) to elucidate the structure of the Nipah virus polymerase complex (the ...

In its structure, DNA contains a pattern for producing ... The process is called the DNA polymerase chain reaction (PCR). (If ...

Then, during the next round of DNA replication, DNA polymerase and the DNA repair ... this unusual complex of DNA and protein is a dynamic structure that depends on telomerase and other cellular ...

Researchers have profiled the molecular structure and features of a key part of the deadly Nipah virus. Experiments in cells showe how changes in the viral polymerase -- a protein involved in viral ...

If your genes could set an alarm clock, EZH1 might be the one ringing the bell. A new study has revealed how this ...

The team focused on T7 DNA polymerase’s thioredoxin binding domain (TBD), which has a structure similar to that of most thermostable polymerases, including Taq. Thioredoxin, which is ubiquitous in ...

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...
