Web30 dec. 2024 · Figure 12.4. 4. Microtubules exhibit dynamic instability. GTP-bound αβ-tubulin dimers are added onto the microtubule. Once the GTP is hydrolyzed, the conformational shift strains the microtubule, which will tend to break apart unless new tubulin dimers are added to stabilize the structure. Again like actin, the tubulin itself has … Web23 sep. 2024 · The article by Su et al 1 documents an interesting example of somatic cell evolution, where a deleterious germline heteroplasmic mitochondrial mutation is frequently lost in mitotic intestinal epithelium but not in adjacent smooth muscle cells. Essentially the epithelium ‘improves’ with age as mutant mitochondrial genomes are purged.
