Spliceosome components include

Explanation:
Spliceosome components are small nuclear ribonucleoproteins (snRNPs), the essential players that drive intron removal from pre-mRNA. The spliceosome is built around these snRNPs (like U1, U2, U4, U5, and U6), each containing a small nuclear RNA and proteins that work together to recognize splice sites and catalyze the two transesterification steps that excise introns and ligate exons, often forming a lariat intermediate. Other cellular components such as DNA polymerases, ribosomes, or lipids do not participate in splicing—DNA polymerases replicate DNA, ribosomes translate mRNA into protein, and lipids have structural or signaling roles rather than splicing functions.
