Since opposite charges attract, the DNA is pulled in toward the histones. A nucleosome is a segment of the DNA wrapped around a core of histones. Here is a view of the double helix -- the subject ...

These groups are called the reading frame. Thus, if the number of bases removed from or inserted into a segment of DNA is not a multiple of three (Figure 4a), the reading frame transcribed to the ...

In these three steps, called one cycle, a new copy of the DNA segment is ready. If there is only one starting copy and each cycle operates with 100% efficiency, making a million copies of the ...

Introduction: The DNA of a Biotech BoomThe global plasmid DNA manufacturing market is entering a transformative era, driven ...

Once scientists have zeroed in on a specific segment of DNA, how do they produce enough copies of that segment for their research? In most cases, the polymerase chain reaction, or PCR, is their ...

Researchers harness the power of the world’s most advanced supercomputers to simulate the inner workings of cellular ...
