There has been tremendous progress in the past few years regarding our understanding of DNA replication in eukaryotes, both yeast and mammals. Many important questions in the field are poised to be ...

Before a cell divides and DNA is passed from one cell to another, a complex process occurs. The DNA strands unwind and separate. Each strand makes a complementary strand by adding the appropriate ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell ...

The DNA is unwound and unzipped. The helix structure is unwound. Special molecules break the weak hydrogen bonds between bases, which are holding the two strands together. This process occurs at ...

Scientists are one step closer to making a biological computer after building basic components for digital devices out of bacteria and DNA. Some scientists believe that, in the future, small ...

Samples are prepared for DNA extraction in a medical clinical laboratory, based at the University of Bristol (Ben Birchall/PA). (PA Archive) Biometrics Commissioner Fraser Sampson said the mistakes ...
