If the expression of every gene depends on a set of transcription regulators, then the expression of these transcription regulat

ors must also depend on the expression of other transcription regulators, and their expression must depend on the expression of still other transcription regulators, and so on. Cells would therefore need an infinite number of genes, most of which would code for transcription regulators?

Answer:

Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns

Explanation:

Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.

What is happening in the food vacuoles that causes the yeast to turn blue?
Rom4ik [11]
Answer;
Food vacuoles that causes the yeast to turn blue indicates active digestive processes in the cell.The blue represents the mature food vacuoles as some yeast cells have now entered, and beginning the digestive process. 

Explanation; 
The ingested yeast cells appear red during early stages of being eaten. Later some of the yeast cells will enter into the food vacuoles to which acidosomes have fused, lowering the pH. The yeast cells within the food vacuole will turn blue, indicating active digestive processes in the cell. It is used for yeast uptake in the paramecium food vacuoles.
