DNA is a double helix structure comprised of nucleotides. A nucleotide, in turn, is made up of phosphate molecule, deoxyribose, and a nitrogenous base. Know the fundamental structure of DNA and the process of DNA replication in this tutorial.

Leading and lagging strand synthesis in these reactions is coupled and the size of the Okazaki fragments produced is typical of those generated in T4 infections. In this study the structure of the DNAs and DNA-protein complexes engaged in these in vitro reactions has been examined by electron ...
Structure of a nucleosome. DNA is looped around a core of eight histone proteins (pairs of four different histone proteins) and connected to adjacent nucleosomes by linker DNA and another histone (H1, not shown). During DNA replication, the histone complexes of nucleosomes are separated; the ...

The knowledge of protein-DNA interactions is essential to fully understand the molecular activities of life. Many research groups have developed various tools which are either structure- or sequence-based approaches to predict the DNA-binding residues in

The ATP-dependent chromatin remodeller DDM1 has a vital role in plant DNA methylation, influencing gene silencing and suppression of transposable elements. The structure of DDM1 in complex with nucleosome in different states of the ATP hydrolysis process reveals the molecular mechanism underlying chroma...
As the Bdnf gene has a complex structure with multiple noncoding exons and a common protein coding exon, we first examined the differential expression of major exon-specific Bdnf transcripts in primary cortical neurons. Each noncoding exon has an independent promoter, and the expression of the ...
