The study of DNA replication started almost as soon as the structure of DNA was elucidated, and it continues to this day. Currently, the stages of initiation, unwinding, primer synthesis ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... functioning and survival of all living organisms. DNA ...

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 ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

In its structure, DNA contains a pattern for producing ... by providing raw nucleobases and a template DNA sample to DNA replication enzymes from bacteria. Because enzymes are little molecular ...

"The replication process is carried out ... G-quadruplex–stalled eukaryotic replisome structure reveals helical inchworm DNA translocation, Science (2025). DOI: 10.1126/science.adt1978 ...

When organisms encounter problems -- what scientists call "replication stress ... bases (represented by G in the DNA code) can fold into a DNA structure called a G-quadruplex, or G4 for ...
