contain dna, which acts as an instruction manual or blueprint for cells on how to create copies of themselves. when an alpha particle hits our dna it can cause damage to a cell's blueprint. cells constantly replicate themselves, but with a broken blueprint the replication process can become cancerous...
damage. the disorder is caused by a gene mutation in a specific type of stem cell. a process known as crispr-cas has been used to correct the mutation in stem cells placed in lab equipment. the edited cells may one day be placed in the bodies of people with sickle cell anemia. the process will hopefully...

- li-mno the saft lm/m cylindrical primary lithium cells are based on lithium-manganese dioxide (li-mno ) chemistry. they feature high surface area spiral electrodes for maximum current pulse capability and an electrolyte formula for excellent performance in the cold. they are designed specifically...
other cells when mounting an immune response. a different population of t cells, the cd + t cells, function as "helper cells". unlike cd + killer t cells, these cd + helper t cells function by indirectly killing cells identified as foreign: they determine if and how other parts of the immune system respond...
high-density polyethylene, and perforated drainage pipes in gravel to collect any water that gets through. it's topped with a -foot layer of dirt to protect the drainage and liner system as trucks drive over it. the waste itself is compacted in two, -foot-thick layers separated by two feet of clean fill. the cells...
important on a subset of t cells called t follicular helper cells (tfh cells). [ ] on tfh cells, cd promotes b cell maturation and function by engaging cd on the b cell surface and therefore facilitating cell-cell communication. [ ] a defect in this gene results in an inability to undergo immunoglobulin...
