2、tion item 130, 3135 title match each 2 points) 1. The following accounts of cell division and biological inheritance are not correct A. does not undergo meiosis, and its inheritance does not follow Mendels genetic rules The laws of B. gene isolation, free association, and sex inheritance can act sim
3、ultaneously in gametogenesis C. treated Escherichia coli with colchicine, doubling its chromosomes D. is an animal cell undergoing meiosis, and gene isolation and free association occur in primary spermatocytes 2 、 cell proliferation is an important life activity in organism. The following is a mito

5、 1 - F - E G H During C.G, the centromere breaks up under the pull of spindle filaments, Chromosome doubling The D.C process must occur after colchicine The processing period should be 2 periods 3 and P53 proteins are proteins synthesized by the P53 gene that bind specifically to DNA. The protein is
6、 available To prevent damage to the DNA replication to provide sufficient time to repair DNA damage; if the repair fails, the P53 protein then Cause apoptosis; if two copies of the P53 gene are mutated, they lose control of cell proliferation and cause cells to become apoptotic 精品学习资料 可选择p d f - - -
