How to capture carbon?5 answersCarbon capture technologies involve the capture of carbon dioxide (CO2) from fuel combustion or industrial processes. These technologies can be applied to different industries such as power generation, hydrogen production, iron and steel, ammonia production, preparation of fossil fuels, and natural gas processing. Major carbon capture technologies include adsorption, absorption, chemical looping, cryogenic distillation, and membrane separation. These technologies are evaluated based on their CO2 capture performance, energy requirement, and environmental impact. Another method for capturing carbon dioxide is by contacting the CO2 with at least one metal carbonate in an aqueous organic solvent at a predetermined temperature. Additionally, devices and systems can be used to capture CO2 in a form that can be stored, processed, and converted to usable products. These systems can be placed in various locations, such as office buildings, apartments, homes, and automobiles, to remove significant amounts of CO2 on a global scale.
How does telomere capture works ?5 answersTelomere capture is a mechanism that stabilizes broken chromosomes by capturing the ends of other chromosomes. This process has been observed in various genomic rearrangements. Telomere capture involves the fusion of broken chromosome ends with telomeric repeats from other chromosomes, resulting in the formation of dicentric chromosomes. Telomere capture has been observed in cases of interstitial inverted duplications with associated terminal deletions, where telomere capture is frequently used to stabilize the broken chromosome ends. Telomere capture can also occur through a series of events involving a 1pter deletion followed by multiple telomere captures, resulting in additive increases in homozygosity towards the telomere. The frequency and diversity of partner chromosomes involved in subtelomeric translocations suggest that telomere capture can stabilize chromosome breakage in humans.
How does telomere capture work ?5 answersTelomere capture is a mechanism used to stabilize broken chromosome ends in genomic rearrangements. It involves the capture of telomeric sequences from other chromosomes to the ends of broken chromosomes. This process has been observed in various types of genomic rearrangements, such as interstitial inverted duplications with associated terminal deletions. Telomere capture can occur through different mechanisms, including the breakage-fusion-bridge cycle mechanism and the mediation of inverted low-copy repeats. Telomere capture has been found to be frequently used for stabilizing broken chromosome ends in these rearrangements. Multiple telomere captures can occur in separate cell lineages, resulting in complex mosaicism of chromosome segments.
