Chromosome packing
WebDNA packaging, 3D animation with advanced narration and labels Description Transcript Keywords Info Each chromosome consists of one continuous thread-like molecule of DNA coiled tightly around proteins, and contains a portion of the 6,400,000,000 basepairs (DNA building blocks) that make up your DNA. WebDNA packing reaches its most condensed state during metaphase in mitosis in preparation for chromosome separation. Chromatin packing is dynamic and undergoes reversible changes in response to changes in gene expression and the cell cycle. Credit: Rao, A., Ryan, K. Fletcher, S. Hawkins, A. and Tag, A.

WebFeb 28, 2015 · CHAPTER 13 DNA Packaging in Chromatin and Chromosomes. C hromosomal DNA molecules of eukaryotes are thousands of times longer than the diameter of the nucleus and must therefore be highly compacted throughout the cell cycle. This folding is accomplished by combining the DNA with structural proteins to make chromatin.
