1.遗传的物质基础是什么? 遗传学是阐明生物遗传(指上下代之间相似的表现)和变异(指亲代和子代之间的差异)规律的科学,探索遗传和变异的物质基础即研究遗传物质的本质,遗传物质的传递及遗传信息实现的科学。生物体的结构和生命活动的基本单位是细胞。而遗传的物质基础就在细胞核内。细胞核像个小球一样悬在细胞质中,它的外面有双层薄膜包围着,把核内和核外分隔开来,核内有一种可被碱性染料着
1. What is the genetic basis of heredity? Genetics is the material basis for elucidating the laws of biological genetics (referring to similar manifestations between generations) and variation (referring to differences between parents and offspring) The nature of genetic material, the transmission of genetic material, and the science of genetic information. The basic unit of biological structure and life activity is cell. The genetic material basis in the nucleus. The nucleus hangs like a pellet in the cytoplasm, surrounded by a double layer of film on its exterior that separates the nucleus from the nucleus. There is a nucleus that can be blocked by a basic dye
