Abstract: The present invention provides a simple method for splitting and loss of a chromosome in yeast. The method for modifying a chromosome in yeast includes preparing a linear chromosome splitting vector (1) having a target sequence (a), a marker gene sequence and (C4A2)n sequence in this order; preparing a linear chromosome splitting vector (2) having a target sequence (b), a centromere sequence of a yeast chromosome and (C4A2)n sequence in this order; and introducing the chromosome splitting vectors (1) and (2) into yeast. Herein, n is each independently an integer of 6 to 10. Although this chromosome splitting vector has a repetitive sequence of 5?-CCCCAA-3?, it can be amplified specifically with PCR, so that a chromosome splitting vector can be prepared significantly simply and easily, compared with the conventional DNA splitting method.
