4 0

RNA polymerase binds to the lac promoter and begins transcribing the stretch of DNA to messenger RNA. Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of the lac promoter 'signals' where the RNA polymerase will bind and where transcription will begin. Promoters are found upstream of a gene to be transcribed.

Mrac [35]

Answer;

The mismatched pair is;

C) receptor proteins — bind with enzymes

Explanation;

- A receptor protein is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell.

-They are generally trans-membrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways. There are two types of receptors: internal receptors and cell-surface receptors.
