This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...
During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...
The dark bands indicate areas where the structure of the chromosome is dense ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein ...

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 ...
DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... The double helix unwinds, and each strand serves as a ...
Watson and Crick's discovery of DNA structure in 1953 revealed a possible ... every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly ...
To link aptamers to DNA strand displacement modules, various methods such as structure-switching aptamers, associative toeholds, hidden toeholds, remote toeholds, transient toeholds, chemical ...
They constantly untangle knots in the DNA strand and create new chemical bonds when a strand of DNA breaks somewhere in the nucleus. "When people read about repairing genetic material, they often ...
In the double helix structure of DNA, thymine forms a base pair with adenine ... DNA polymerase enzymes use the existing DNA strand as a template and add the complementary nucleotides, including ...
the AMP is transferred to the 5’-end of the 5’-phosphate-terminated DNA strand to form DNA-adenylate — an inverted pyrophosphate bridge structure, AppN. In this reaction, the 5’-phosphate oxygen of ...
The RNA cloud formed around genes regulates their readout into RNA. Triplexes help define where in the genome a cloud forms. Proteins and other fl ...
