WebApr 6, 2024 · A double-strand DNA break (DSB) occurs or arises when both strands of the DNA duplex are severed, often as the result of ionizing radiation. They are particularly deleterious as the DNA ends... WebNov 7, 2024 · Double-strand break repairs (DSBs) are when the phosphorous sugar backbone of the DNA molecule is broken. They are very dangerous and cytotoxic to the cell so the cell must act quickly to...

WebOct 13, 2004 · A strain of Yarrowia lipolytica isolated from a tropical estuarine environment showed the presence of a double-stranded RNA. The double-stranded RNA had a molecular size of 5kb and a G+C content of 61 mole%. The strain was not a killer. No specific physiological function could be assigned to this plasmid. WebA double-stranded break (DSB) in DNA is the most toxic type of DNA damage; it can be induced by either X-rays or chemicals, including anticancer agents. If DSBs in DNA cannot be repaired, cells can die by apoptosis to be removed from tissues. henry cremation \u0026 funeral services mo

The NHEJ pathway recruits multiple proteins, including KU70 and KU80, and does not require a homologous template [ 9 ]. WebNov 12, 2024 · 1 Answer Sorted by: 7 Ionizing radiation does cause single-strand breaks and other kinds of DNA lesions that are not double-strand breaks. However, double-strand breaks are the most difficult to repair and are thus the most likely DNA damage type to result in mutation and / or cell death. henry creel x will ao3
