Chromosome compaction
WebJul 30, 2024 · There are a number of ways that chromosomes are compacted. In the first level of compaction, short stretches of the DNA double helix wrap around a core of eight histone proteins at regular intervals along the entire length of the chromosome (Figure 3). The DNA-histone complex is called chromatin. WebApr 16, 2024 · The processes that manage DNA, whether it be replication, repair, gene expression, or chromosome segregation, must act on DNA in a way that the processes sense whether they are acting on the same or different molecules by tracking the three-dimensional path of individual DNA molecules.
