Quizlet made its first acquisition in March 2021, with the purchase of Slader, which offered detailed explanations of textbook concepts and practice problems, and eventually incorporated it into its paid platform, Quizlet Plus. [20] [21] [22] In November 2022, Quizlet announced a new CEO, Lex Bayer, the former CEO of Starship Technologies. [23]
After a request comes in from a qualified provider, the request will go through the prior authorization process. The process to obtain prior authorization varies from insurer to insurer but typically involves the completion and faxing of a prior authorization form; according to a 2018 report, 88% are either partially or entirely manual.

Transcription preinitiation complex, represented by the central cluster of proteins, causes RNA polymerase to bind to target DNA site. The PIC is able to bind both the promoter sequence near the gene to be transcribed and an enhancer sequence in a different part of the genome, allowing enhancer sequences to regulate a gene distant from it.
A 5' cap (also termed an RNA cap, an RNA 7-methylguanosine cap, or an RNA m 7 G cap) is a modified guanine nucleotide that has been added to the "front" or 5' end of a eukaryotic messenger RNA shortly after the start of transcription. The 5' cap consists of a terminal 7-methylguanosine residue that is linked through a 5'-5'-triphosphate bond to ...
Shortly after transcription is initiated in eukaryotes, a pre-mRNA's 5' end is modified by the addition of a 7-methylguanosine cap, also known as a 5' cap. [9] The 5' capping modification is initiated by the addition of a GTP to the 5' terminal nucleotide of the pre-mRNA in reverse orientation followed by the addition of methyl groups to the G ...
Even for doctors trained in addiction medicine — motivated to treat opioid addicts with buprenorphine and able to work within Medicaid’s numerical limits — there are still roadblocks. Kentucky’s Medicaid program, like those of many other states, requires prior authorization before it agrees to pay for the medication.
As stated by the authors, [6] this book was aimed at professional biologists and assumes considerable prior knowledge. They have also published a summary of their arguments in Nature [7] as well as a presentation of their ideas for a general readership under the title The Origins of Life — From the Birth of Life to the Origins of Language.

RNA polymerase is composed of a core and a holoenzyme structure. The core enzymes contains the catalytic properties of RNA polymerase and is made up of ββ′α2ω subunits. This sequence is conserved across all bacterial species. The holoenzyme is composed of a specific component known as the sigma factor (σ-factor). The sigma factor ...
