To discover the key molecule of life that carries secret of life, scientists made many reakthrough discoveries. Read some of the key discoveries in the list below. You will find a able below listing name of the scientists who contributed in the discovery. Write description f each discovery of scientist in appropriate box in the Table. A. Factor/Gene exists in organisms that is responsible for inheritance. This factor transmits from parents to the offspring as a unit of characteristic. B. Genes are arranged in a linear fashion on chromosome, like beads on a string. C.The nucleus of cell contains a mixture of unique compounds called "nuclein". D. The molecule that carries the heritable information is DNA. E. In all cellular DNAs: number of the "A" equals the number of "T" the number of "G" equals the number of "C". F. Solved the puzzle and proposed double-helical model for DNA.
