Your answer should describe what each item is and how it functions in the cell. Diagrams, structure and sequence information should be included in your answer, as necessary. 1. Yeast artificial chromosome 2. RNA interference 3. Proteomics

In both prokaryotes and eukaryotes, primary RNA transcripts undergo various alteration or processing events to become mature RNAs: The three commonest types are: 1, nucleotide removal by nucleases; 2, nucleotide addition to the 5’- or 3’-end, 3, nucleotide modification on the base or thesugar

Most of the eukaryotic genes are mosaic (嵌合体), consisting of intervening sequences separating the coding sequence ◼ Exons (外显子): the coding sequences ◼ Introns (内含子) : the intervening sequences ◼ RNA splicing: the process by which introns are removed from the pre￾mRNA. ◼ Alternative splicing (可变剪接): some pre-mRNAs can be spliced in more than one way , generating alternative mRNAs. 60% of the human genes are spliced in this manner

一、 hnRNA 二、 pre-mRNAs 三、 hnRNP 四、 snRNPs 五、pre-mRNA processing The alternative mRNA processing is the conversion of pre-mRNA species into more than one type of mature mRNA

一、基因表达的概念 1、基因（gene）：从遗传学讲，基因就是遗传的基本单位或单元，具有编码RNA或多数情况下编码多肽功能的信息单位。从分子生物学看，基因是负载特定遗传信息的DNA分子片段
