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 ...

The double helix structure of DNA is so famous it serves as a sort ... each other like normal (adenine to thymine on the opposite strand, cytosine to guanine) cytosines on the same strand hook ...

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 ...

In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various ...

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 ...

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 ...

Briola and co-authors determined the structure of the human CTF18 clamp loader bound to PCNA to high resolution, analyzed the structure, and tested a new mechanism involving a human-specific Ctf18 ...
