• Chromatin.net: Chromatin is that portion of the cell nucleus which contains all of the DNA of the nucleus in animal or plant cells. (A small amount of special DNA is also found in the mitochondria of the cell cytoplasm outside of the cell nucleus.)
• Chromosome at the National Human Genome Research Institute: One of the threadlike packages of genes and other DNA in the nucleus of a cell.
• Euchromatin Network: Euchromatin is that portion of the genome that is most active in gene transcription within the animal cell nucleus. It is in marked contrast to heterochromatin, which is the least active. And yet, either form of chromatin can be converted to the other, conversion to euchromatin being associated with new gene activation for RNA synthesis, and conversion to heterochromatin being associated with new gene repression for RNA synthesis. // Together with the Euchromatin Network, we are developing forums on all aspects of euchromatin, its composition, activity, control, and significance. We welcome your comments and suggestions in the design of these forums, and your participation in their on-going discussions.
• Spanish Omelette: analogy to fundamental dogma: The following is a good way to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetic vs. environmental causes of cell defects.
• System Biology, the 21st century Science: Systems biology is the study of an organism, viewed as an integrated and interacting network of genes, proteins and biochemical reactions which give rise to life. Instead of analyzing individual components or aspects of the organism, such as sugar metabolism or a cell nucleus, systems biologists focus on all the components and the interactions among them, all as part of one system....
