问题 下述各项变异能导致细菌L型的是
选项 A:RNA B:DNA C:细胞壁 D:细胞膜 E:菌落
答案 C
解析 细菌很容易变异,如某些细菌在抗生素作用下发生细胞壁的变异,形成细胞壁缺陷的细菌L型,但此变异只是细菌表型的改变,而非遗传性状的改变。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
