Enzymes from Calf Thymus That Might Be Involved in DNA Repair,ell transformation that will eventually lead to cancer. Radiation and substances that directly or indirectly alter the molecules of DNA are potentially mutagenic and carcinogenic, thus behaving as genetic toxins. Detrimental agents of this type are natural or artificial components of the environment in which we all presently live.作者: 根除 時間: 2025-3-22 11:30
