Question

by the 1880s more advanced microscopes were being developed that allowed for even more detailed observations of the microscopic world. during this time walter sutton and theodor boveri were responsible for identifying the chromosome as the hub for heredity—forever linking genetics and cytology. later discoveries further confirmed and solidified the role of the cell in heredity, such as james watson and francis crick’s studies on the structure of dna. a fourth (new) premise of the cell theory is that dna is passed from original parent cells to the daughter cells during cell division. what development helped contribute to this new premise? they discovered further confirmed and solidified the role of the cell in heredity, james watson & francis crick’s studies on the structure of dna. a fifth (new) premise of the cell theory is that all cells of an organism and organisms of the same species are for the most part structurally and chemically the same. how does the work of thompson support this premise of the new cell theory?

Explanation:

The text mentions that James Watson and Francis Crick's studies on the structure of DNA further confirmed the role of the cell in heredity, which is relevant to the new premise about DNA passing from parent - to - daughter cells. Regarding Thompson, since no information about Thompson's work is given in the provided text, we cannot answer the second part. But for the first question about the development contributing to the new premise about DNA passing during cell division, it's the studies on DNA structure by Watson and Crick.

Answer:

The development that helped contribute to the new premise (DNA is passed from original parent cells to daughter cells during cell division) is James Watson and Francis Crick's studies on the structure of DNA.
