The process by which small interfering RNAs target cognate mRNA molecules for degradation. The process by which proteins required for 3'-end transcript processing become associated with the RNA polymerase II holoenzyme complex and the 3' end of a transcript. Formation of a complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2 (either eIF2 in eukaryotes, or IF2 in prokaryotes). In prokaryotes, fMet-tRNA (initiator) is used rather than Met-tRNA (initiator). The process by which a single-stranded small RNA associates with the RNA-initiated silencing complex (RISC); occurs as part of a process of gene silencing by small RNA. Joining of the large subunit, with release of IF2/eIF2 and IF3/eIF3. This leaves the functional ribosome at the AUG, with the methionyl/formyl-methionyl-tRNA positioned at the P site. The joining of the small ribosomal subunit, ternary complex, and mRNA. The process by which a cellular component is synthesized, aggregates, and bonds together. Includes biosynthesis of constituent macromolecules, and those macromolecular modifications that are involved in synthesis or assembly of the cellular component. Assembly of a spliceosomal complex containing the intact pre-mRNA and all of the spliceosomal snRNPs. This occurs when the tri-snRNP associates with the pre-mRNA and associated snRNPs in an ATP-dependent manner. The aggregation, arrangement and bonding together of proteins and RNA molecules to form a ribonucleoprotein complex. The cellular process by which a complex containing RNA and proteins is synthesized, aggregates, and bonds together. Includes the biosynthesis of the constituent RNA and protein molecules, and those macromolecular modifications that are involved in synthesis or assembly of the ribonucleoprotein complex. Any process carried out at the cellular level by which macromolecules aggregate, disaggregate, or are modified, resulting in the formation, disassembly, or alteration of a macromolecular complex. The aggregation, arrangement and bonding together of a set of macromolecules to form a complex, carried out at the cellular level. Recognition of the pre-mRNA branch site sequence by components of the assembling spliceosome. The formation of a tri-snRNP complex containing U4 and U6 (or U4atac and U6atac) snRNAs and U5 snRNAs and associated proteins. This includes reannealing of U4 and U6 (or U4atac and U6atac) snRNAs released from previous rounds of splicing to reform the U4/U6 snRNP (or U4atac/U6atac snRNP) as well as the subsequent association of the U5 snRNP with the U4/U6 snRNP (or U4atac/U6atac snRNP) to form a tri-snRNP that is ready to reassemble into another spliceosome complex. The aggregation, arrangement and bonding together of proteins and RNA molecules to form a small-subunit processome. The aggregation, arrangement and bonding together of the spliceosome, a ribonucleoprotein apparatus that catalyzes nuclear mRNA splicing via transesterification reactions. The aggregation, arrangement and bonding together of proteins and RNA molecules to form a 90S preribosome. The aggregation, arrangement and bonding together of proteins and RNA molecules to form a cytoplasmic mRNA processing body. Formation of a catalytic spliceosome complex ready to perform the first splicing reaction. This occurs by an ATP-dependent conformational change of the pre-catalytic spliceosome. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. The aggregation, arrangement and bonding together of the mature ribosome and of its subunits. Selection of a splice site by components of the assembling spliceosome. The aggregation, arrangement and bonding together of proteins and a snoRNA to form a small nucleolar ribonucleoprotein (snoRNP) complex. The aggregation, arrangement and bonding together of a set of macromolecules to form a complex. The aggregation, arrangement and bonding together of one or more snRNA and multiple protein components to form a ribonucleoprotein complex that is involved in formation of the spliceosome. Rearrangement of the pre-catalytic spliceosome containing U4 (or U4atac) and U1 (or U11) snRNPs to unpair U4 (or U4atac) from U6 (or U6atac) and release it from the spliceosomal complex along with U1 (or U11). The aggregation, arrangement and bonding together of proteins and RNA molecules to form a stress granule. Structural rearrangements of the spliceosome complex, containing RNA to be spliced, to generate a catalytic conformation. Conformational rearrangement of the spliceosomal complex containing the RNA products from the 1st step of splicing to form the catalytic site for the second step of splicing. Assembly of a spliceosomal complex containing the SL RNA and the pre-mRNA to be joined, as well as all the spliceosomal snRNPs involved in trans leader splicing. Formation of the trans leader spliceosome brings together the quadruple SL/U4/U5/U6 snRNP and the complex of the U2 snRNP with the splice site of the pre-mRNA. Formation of a quadruple snRNP complex composed of the spliced leader (SL) RNA along with the U4/U6-U5 tri-snRNP complex. Interactions that may facilitate this include a duplex between the SL and U6 RNAs and interactions between the U5 RNA and the exon sequence at the 5' splice site within the SL RNA.
