Quiz zum Vortrag
Which of the control mechanisms below is NOT a means of controlling gene expression in eukaryotes?
- Nucleotide
- Transcriptional
- RNA stability
- Translational
Under hypoxia conditions, a cell synthesizes a transcription factor. What is it called?
- HIF-1
- HIF-2
- GLUT1
- GLUT2
- Two transcription factors, called GLUT1 and GLUT3.
Which of the following statements is NOT correct?
- The HIF-1 factor helps the cell to combat toxic conditions that originated due to higher oxygen levels.
- Under hypoxia conditions, the regular cells, as well as cancer cells, synthesize the transcription factor called HIF-1.
- HIF-1 factor favors elevated levels of expression of the seven enzymes of the glycolysis pathway during hypoxia condition.
- HIF-1 factor binds to the particular class of genes in the DNA which helps in the survival of cells at low oxygen concentrations.
- The transcription factor HIF-1 helps in the movement of glucose to the interior of the cell by favoring the formation of GLUT1 and GLUT3 proteins.
What do you mean by the control of gene expression?
- Controlling the process of transcription and hence synthesis of specific mRNA and protein molecules.
- Controlling the permeabilities of the cell membrane and mitochondrial membrane for water.
- Controlling the fluidity of cell membrane by regulating ion movement.
- Controlling the amounts of energy in the form of ATP and GTP.
- Controlling the amounts of rRNA and tRNA to regulate.
