the inter-relationship between DNA replication and nuclear structure, and the temporal order of replication. A topic conspicuously missing from this section is establishment of sister chromatid ...

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 ...

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 several locations on a DNA molecule ...

Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double ... This process is essential for the ...

MSK researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer.

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 ...

We employ fully reconstituted yeast and human DNA replication systems to investigate the structure and biochemical mechanism of the eukaryotic replication machinery. A particular focus of the lab is ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

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 ...
