Visual Biology of Nuclear Dynamics: From Micro- to Nano-dynamics of Nuclear Components,m. If you continue the live cell observation, you will easily learn that the cell nucleus does not undergo any significant morphological changes until it reaches the mitosis, where the nuclear envelope and the chromosomes show dynamic structural changes. Because of these morphological properties, th

Functional Organization and Dynamic Aspects of Nucleoli During the Cell Cycle,, it has been generally thought to be the site of ribosome biogenesis. Inner nucleolar DNA sequences encode 18S, 5.8S and 28S ribosomal RNAs and in the nucleolus, many ribosomal proteins and nascent ribosomes are detected (.; .). In metabolically active animal and plant somatic cells and in yeast, t

Gene Selectors Consisting of DNA-Binding Proteins, Histories, and Histone-Binding Proteins Regulateunctional player, namely, protein. Transcription is the first step in gene expression. Since the temporal and spatial regulation of gene expression define cellular identity, transcription is the most critical and fundamental step in the cellular functions of a gene. We have classified transcriptiona

Regulation of Chromatin Structure by Curved DNA: How Activator Binding Sites Become Accessible,s of approximately 1×10. m in diameter. To greater or lesser degrees, all organisms compact their DNA. Biologically important DNA regions, such as the origins of DNA replication, regulatory regions of transcription, and recombination loci, must all be compacted. The tightly constrained DNA, however,
