The Hershey-Chase experiment, in which bacteria were infected with radioactively labeled bacterial virus, provided evidence that DNA carries genetic information by showing that A. the bacterial virus injected its 35S-labeled proteins into the cell. B. blender treatment after infection with virus prevented the production of progeny virus particles. C. the production of progeny virus required the injection of viral DNA into the cell. D. 32P-labeled bacterial virus could not produce progeny virus after blender treatment.

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
