Fill in the Blanks in the "Level of Transcription" Column

question 32

Short Answer

Fill in the blanks in the "level of transcription" column of this table with (+) for high levels of transcription, (+/-) for Moderate levels of transcription, and (-) for minimal levels of transcription of the lac operon. Consider regulation by both the lac repressor and CAP (catabolite activator protein). The strain is wild type with no partial diploidy. The first line is filled in for reference. $\begin{array}{|lc|}\hline Moderate ~conditions & Level ~of ~transcription\\\hline ~ high~ glucose, ~no~ lactose&-\\\hline no ~glucose, ~high ~lactose\\\hline high ~glucose, ~high~ lactose\\\hline no ~glucose, ~no~ lactose\\\hline\end{array}$
