The three mRNAs that encode the capsid proteins of polyoma virus are produced by the excision of different sequences from continuous transcripts of the L strand of viral DNA. All three of the mRNAs have long half lives, and the larger species are not converted to the smaller ones to any measurable extent within the cytoplasm. Therefore the cytoplasmic proportions of late polyoma mRNAs are predetermined by splicing that is confined to the nucleus of the infected cell and which is complete by the time that mRNA is transported to the cytoplasm.
编码多瘤病毒衣壳蛋白的三种信使核糖核酸（mRNA）是通过从病毒DNA的L链连续转录本中切除不同序列而产生的。所有这三种mRNA都具有较长的半衰期，并且在细胞质中，较大的mRNA种类不会以任何可测量的程度转化为较小的种类。因此，晚期多瘤病毒mRNA在细胞质中的比例是由仅限于受感染细胞核内的剪接预先确定的，并且在mRNA转运到细胞质时剪接已经完成。
