Assume that Staphylococcus aureus grows on nutrient agar with up to and including 15% (w/v) NaCl, while Escherichia coli cannot

Nutka1998 [239]

This means that Staphylococcus aureus is more tolerant to salt (NaCl), however, E. coli is sensitive to NaCl concentrations more than 10%. This also means that Staphylococcus has more fluid in its cytoplasm, as compared to E. coli, which enables it to tolerate in high salt concentration. Further, this also indicates the ability of both microbes to grow on different media compositions and have different nutritional requirements.

How many triple codons would you need to make the 6 chain protein?

kakasveta [241]

Some amino acids are encoded by more than one codon, inasmuch as there are 64 possible base triplets and only 20 amino acids. In fact, 61 of the 64 possible triplets specify particular amino acids and 3 triplets (called stop codons) designate the termination of translation.
