Answered Questions From Chapter 4
-
- Genes X and Y are similar due to their similar folding pattern under their respective hours.
- Most spots would be yellow at the first point because...
- The technical reason is that red and green would be mixed, making yellow.
- The biological reason is that this indicates the beginning of transcription, meaning that no change has occurred.
- The gene TEF4 was repressed, as shown in Figure 4.12. Because glucose was the only available form of energy, the depletion of it caused the cell to not have enough energy to perform the transcription of the gene, causing it to be repressed. Campbell mentions that specifically, genes involved in protein synthesis are reduced in environments of low energy.
- As stated above, the cell is in an energy saving mode. When this occurs, genes begin to change their expression in order to compensate for this change in energy. Some genes reduce their expression, TEF4, and some induce their expression. Because TCA is an energy metabolic gene, it was induced in order to produce more energy for the cell.
- Since these genes are in a common pathway already, the reaction can be catalyzed by a common transcription factor. This allows for each gene in the pathway to be controlled simultaneously.
- Because TUP1 is a repressor for glucose-repressed genes, the absence of TUPI would cause the genes to no longer be repressed with the presence of glucose. Consequently, the spots would be red because transcription would be taking place.
