Answer:
<em>Staphylococcus aureus</em>
Explanation:
According to the rule of binomial nomenclature, the name of the organism is written in two parts that are-
1. Generic name- The first name which signifies the genus of the organism, the word represents the noun of the organism, the first letter of the word is always uppercase that is like in the "Staphylococcus"
2. The specific epithet-the second name of the organism represents the species which is usually a noun, and the first letter of species is always written in lowercase like in the aureus.
The scientific name should be written either in the italicised form or if not possible to write in the italicised form than underline the name.
Thus, <em>Staphylococcus aureus </em>is correct.

Please find the detailed explanation of this statement below
Explanation:
Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.
However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.
Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
