Who discovered multiple myeloma?Question:Who discovered multiple myeloma?Understanding multiple myeloma:Multiple myeloma is cancer of the plasma cells. Although it does not have any initial symptoms, delayed symptoms include bone pain, bleeding and anemia, and frequent infections.Answer...
Szostak, who solved a major puzzle in biology; they discovered that chromosomes don't degrade when they replicate because it's all to do with how telomerase makes telomeres to protect the ends of the chromosomes. Their discoveries led to a new understanding of how cells work and opened new ...
In the 2000s, Dr. Thilly and his team discovered that point mutations — when a single nucleotide pair is changed, inserted, or deleted from a DNA or RNA sequence of a genome — arise in certain stem cells of fetal organs, when polymerases, the enzymes that create DNA molecules, make “...
Obituary Edmond Fischer (1920–2021) Nobel-winning biochemist who discovered a ubiquitous cell-regulatory mechanism. Edmond Fischer discovered the first example of reversible protein phos- phorylation, a process that regulates most aspects of cell life. Two classes of enzymes, protein kinases and ...
is the protein molecule responsible for making blood red. Named by combining the Greek word for blood — haima — with the idea of globs, hemoglobin is like a little blood blob, explains the Royal Society of Chemistry. In red blood cells, hemoglobin is responsible for the transport of oxygen...
Discovered Remains in China Suggest Human Species With Big Heads Once Roamed Earth This photograph taken in Johannesburg on November 4, 2021 shows a full-scale reproduction of the skull of a hominid named Leti, named after a seTswana word "letimela" meaning "t...
How was cytokinin discovered? The cytokinins were discoveredas a result of efforts to find factors that would stimulate plant cells to divide. ... These investigations led Skoog, Miller and co-workers in 1955 to the isolation and identification of kinetin, a highly-active cell division factor, ...
They discovered that the lactase gene variants seen in East Asian people altered the activity of three genes in immune cells, causing them to expand in number. Based on this result, the study authors think it's possible that these variants were selected for because they somehow enhanced the ...
making long-term studies on tissues difficult. But these cells had a particular cancerous mutation that allowed them to flourish. Named after the African American woman they were obtained from,Henrietta Lacks, this cell line –“HeLa,” as it is abbreviated – is still used for medical research...
