◐Partially SupportedIn gene editing for sickle cell anemia, researchers modify harvested bone marrow stem cells by introducing messenger RNA (mRNA) for Cas9 and guide RNA.◐Partially SupportedCurrent medical practice for sickle cell anemia involves mobilizing and harvesting the patient's bone marrow stem cells, often stimulated by medication.◐Partially SupportedSickle cell anemia is caused by a mutation leading to red blood cells that sickle, impairing function and potentially causing blood vessel occlusion.◐Partially SupportedSickle cell anemia is a single point mutation that changes one amino acid, resulting in significant downstream negative health consequences.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

◐Partially Supported

Having one copy of the sickle gene provides protection against malaria.

◐Partially SupportedProtein synthesis begins with DNA, which codes for proteins synthesized via transcription to mRNA and translation by ribosomes using amino acids.

◐Partially SupportedGene editing for sickle cell anemia aims for a one-time curative treatment by modifying bone marrow stem cells.

◐Partially SupportedIntroducing DNA, mRNA, or protein for Cas9 into a cell will result in the cell producing Cas9 protein.

◐Partially SupportedGene editing for sickle cell disease modifies a different gene to allow the fetal hemoglobin gene to turn on, rather than directly correcting the mutation.

◐Partially SupportedDNA can be introduced into cells using viruses or by electroporation, which involves zapping cells with an electrical current to rupture their membranes and allow DNA entry.
