WebApr 2, 2024 · The third level of packaging involves the packaging of 30 nm solenoid fibre itself with other proteins to form protein scaffold. This packages the DNA further by a packing ratio of around 1000 in euchromatin. A even more dense and tightly packed protein scaffold is seen in mitotic chromosomes, having a packing ratio of around 10,000. WebJan 1, 2016 · The DNA molecule is much-much longer than the most extended chromosomes fibers. The packing ratio was defined as the proportion of the DNA double helix and the length of the chromosome fibers. In the human chromosome complement, the packing ratio was estimated to be more than 100:1 at metaphase.

WebDNA packaging. 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. The way DNA is packaged into chromatin is a factor in how protein production is controlled. Duration: 1 minutes, 30 seconds Web(4) Exact folding and packing patterns of chromatids of different chromosomes are thought to vary in some specific ways. Thus each metaphase chromatid is composed of tightly folded single chromatin fibre of 200-500 A diameter. The exact 3-dimensional configuration of nucleoprotein fibre in any given chromatid is not constant.
