Answer:
Some substance in the infectious S strain could change the harmless R strain into the more lethal form.
Explanation:
These first type of experiments where crucial to advance in DNA knowledge.
In one experiment, they treated the material with enzymes that destroy all proteins. This is important because scientist notice that there was something else that was causing the strain to change into a lethal form and was heritable (DNA). Know a days we know that plasmids are responsible for such transformation.
Answer:
During transcription, a strand of RNAm is obtained from DNA.
On the other hand, the translation is the process of peptide synthesis, from mRNA. This last process occurs in the cytoplasm, and is mediated by the ribosomes.
Regarding your last question, this last process is called translation, since in this process we pass from genomic language (nitrogenous bases) to amino acids (constituents of peptides).
