Yeast artificial chromosomes (YACs) have become essential research tools as they enable large fragments of DNA to be cloned. In order to overcome several disadvantages of YACs, including chimaerism and instability, several complementary bacterial artificial chromosome (BAC) vectors have been developed. More recently, attempts are being made to construct artificial chromosomes in mammalian cells (MACs).
酵母人工染色体(YACs)已成为重要的研究工具,因为它们能够克隆大片段DNA。为了克服YACs的几个缺点,包括嵌合现象和不稳定性,人们开发了几种互补的细菌人工染色体(BAC)载体。最近,人们正在尝试在哺乳动物细胞中构建人工染色体(MACs)。
