Recombinase polymerase amplification (RPA) is a single tube, isothermal alternative to the polymerase chain reaction (PCR). [1] By adding a reverse transcriptase enzyme to an RPA reaction, it can detect RNA as well as DNA, without the need for a separate step to produce cDNA.
Replication protein A (RPA) is the major protein that binds to single-stranded DNA (ssDNA) in eukaryotic cells. [1] [2] In vitro, RPA shows a much higher affinity for ssDNA than RNA or double-stranded DNA. [3] RPA is required in replication, recombination and repair processes such as nucleotide excision repair and homologous recombination.
Robotic process automation (RPA) is a form of business process automation that is based on software robots (bots) or artificial intelligence (AI) agents. [1] RPA should not be confused with artificial intelligence as it is based on automation technology following a predefined workflow. [ 2 ]
Alternate form of carcinogenic substances may also be used to minimize the risk of exposure. In the case of carcinogens which pose a danger through inhalation, pastes or pellets can be used to avoid the possibility of airborne dust. Volatile liquids can also potentially be substituted with paste forms to avoid excessive formation of vapors. [7]
AP site formation can also be caused by various base-modifying chemicals. Alkylation, deamination, and oxidation of individual bases can all lead to the weakening of the glycosyl bond, so exposure to agents that cause those modifications can encourage AP site formation. [2] Ionizing radiation can also lead to AP site formation. Irradiated ...
Abra hopes the structures can help turn things around for some of Brazil’s vulnerable and endangered species, like the Groves’ titi, the Schneider’s marmoset, and the Guiana Spider Monkey.
Many big companies are pulling workers back to the office five days a week. The Big Four — EY, Deloitte, PwC, and KPMG — are sticking with hybrid work policies.
Dubbed the super catch-up, workers aged 60 to 63 this year can make a catch-up contribution of $11,250 instead of $7,500, bringing their total allowable 401(k) contribution to $34,750.
