Abstract
Xenopus oocytes transcribe cloned yeast tyrosine tRNA genes and process the RNA. The processing includes base modifications, addition of the CCA end, and splicing of the intervening sequence. The primary transcript has a 5' leader extension which varies considerably in seuqence and in length between different tRNATyr loci, but is nevertheless present in all of them.
摘要
非洲爪蟾卵母细胞转录克隆的酵母酪氨酸tRNA基因并对RNA进行加工。这种加工包括碱基修饰、添加CCA末端以及剪接间隔序列。初级转录本有一个5'前导序列延伸，其在不同的tRNATyr基因座之间的序列和长度有很大差异，但在所有这些基因座中都存在。
