Chromosomal DNA Replication on a Protein “Chip”

Protein Kinase A is required for chromosomal DNA replication

Passage through mitosis resets cells for a new round of chromosomal DNA replication [1]. In late mitosis, the pre-replication complex - which includes the origin recognition complex (ORC), Cdc6 and the minichromosome maintenance (MCM) proteins - binds chromatin as a pre-requisite for DNA replication. S-phase-promoting cyclin-dependent kinases (Cdks) and the kinase Dbf4-Cdc7 then act to initiate...

DNA chip replication for a personalized DNA chip.

We report the replication technology of DNA chip using by sequence specific localization of nucleic acids via hybridization and electric transfer of the nucleic acids onto a new substrate without losing their array information. The denatured DNA fragments are first spotted and UV-cross-linked on a nylon membrane. The membrane is then immersed and hybridized in a DNA mixture solution that contai...

Analyzing DNA-protein interactions on a chip

Gene expression is regulated by multi-protein complexes binding to short non-coding regions of genomic DNA, called cisregulatory elements. A long-term goal of genomics is to identify and annotate all essential elements of the genome. Most coding elements of the genome have been identified and annotated; however, most regulatory elements have not. This chapter describes a method for the high thr...

Cell cycle control of chromosomal DNA replication.

Accurate replication and segregation of chromosomal DNA is essential for high-fidelity transmission of genetic information from generation to generation. Eukaryotic cells typically replicate by first duplicating their chromosomes during the S phase followed by their segregation between two daughter cells during the M phase. Over recent years, advances in our understanding of this process at the...
