Describe the role of the various types of nucleic acids in the storage and expression of information in living organism

An autoradiograph is a picture on a x-beam film or atomic emulsion created by the example of rot discharges (e.g., beta particles or gamma beams) from a circulation of a radioactive substance
The Meselson-Stahl investigate E. coli was basically copied in 1958 by Herbert Taylor on the chromosomes of bean root-tip cells, by utilizing a cytological method. Taylor put root cells into an answer containing tritiated thymidine ([3H]thymidine)— the thymine nucleotide named with a radioactive hydrogen isotope called tritium. He permitted the cells to experience mitosis in this arrangement so that the [3H]thymidine could be fused into DNA. He then washed the tips and exchanged them to an answer containing nonradioactive thymidine. Expansion of colchicine to such a readiness restrains the shaft contraption so that chromosomes in metaphase neglect to discrete and sister chromatids stay \"entwined\" by the centromere.
The cell area of 3H can be dictated via autoradiography. As 3H rots, it transmits a beta molecule (a fiery electron). In the event that a layer of photographic emulsion is spread over a cell that contains 3H, a substance response happens wherever a beta molecule strikes the emulsion. The emulsion can then be created like a photographic print so that the emanation track of the beta molecule shows up as a dark spot or grain. The cell can likewise be recolored, making the structure of the cell noticeable, to recognize the area of the radioactivity. As a result, autoradiography is a procedure in which radioactive cell structures \"take their own photos.\" It demonstrates the outcomes watched when colchicine is included amid the division in [3H]thymidine or amid the resulting mitotic division. It is conceivable to translate these outcomes by speaking to every chromatid as a solitary DNA atom that recreates semiconservatively
