思路分析
Consider the biological context of uracil-rich ribonucleoproteins labeled U1, U2, etc. These small nuclear ribonucleoproteins (snRNPs) are components of a complex involved in RNA splicing, where pre-mRNA is processed to remove introns.

In eukaryotes, what does the mRNA transcript contain?
In eukaryotic cells, the initial RNA transcript (pre-mRNA) contains non-coding segments called [ Select ] spliceosomes promoters exons introns polymerase that intervene between coding regions. Before the RNA leaves the nucleus, a large protein-RNA complex called the [ Select ] introns polymerase exons ribosomes spliceosomes removes these non-coding parts and joins the coding regions, known as [ Select ] promoters spliceosomes polymerase exons introns together. This process allows a single gene to encode multiple different proteins depending on which segments are treated as coding.
