43S preinitiation complex         
A PROTEIN COMPLEX COMPOSED OF THE 40S RIBOSOMAL SUBUNIT PLUS EIF1A, EIF3, AND EIF2-GTP-BOUND METHIONYL-INITIATOR METHIONINE TRNA.
Draft:43S preinitiation complex; 43S PIC
The 43S preinitiation complex (43S PIC) is a ribonucleoprotein complex that exists during an early step of eukaryotic translation initiation. The 43S PIC contains the small ribosomal subunit (40S) bound by the initiation factors eIF1, eIF1A, eIF3, and the eIF2-Met-tRNAiMet-GTP ternary complex (eIF2-TC).
Transcription preinitiation complex         
  • 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.
COMPLEX OF PROTEINS NECESSARY FOR GENE TRANSCRIPTION IN EUKARYOTES AND ARCHAEA
Assembly of the transcription preinitiation complex
The preinitiation complex (abbreviated PIC) is a complex of approximately 100 proteins that is necessary for the transcription of protein-coding genes in eukaryotes and archaea. The preinitiation complex positions RNA polymerase II at gene transcription start sites, denatures the DNA, and positions the DNA in the RNA polymerase II active site for transcription.

STATE OF MIND IN WHICH AN INDIVIDUAL HOLDS A BELIEF THAT THEY ARE, OR ARE DESTINED TO BECOME, A SAVIOR
Messianic Complex; Christ complex; Messianic complex; Saviour complex; Savior complex; Messiah Complex; Messiah complex (self-concept); Savior Complex; Bodhisattva complex; Bodhisatta complex
A messiah complex (Christ complex or savior complex) is a state of mind in which an individual holds a belief that they are destined to become a savior today or in the near future. The term can also refer to a state of mind in which an individual believes that they are responsible for saving or assisting others.
