Reporter genes can be used to indicate not only the amount of gene expression, but also the sites of the expressed proteins.
举一反三
- The expression products of all genes are proteins.
- Some genes can be expressed in different ways to generate multiple gene products from a single segment of DNA.
- Eukaryotic genes have additional steps and more regulatory binding sites controlled by more regulatory proteins. Besides, nucleosomes and their modifiers influence genes expression.
- which of following do not belong to pathogenic variations of the endogenous genes ( ) A: gene amplification B: abnormal gene expression C: invasion of the foreign genes D: gene arrangement E: point mutation
- Which of the following methods is not used by cells to regulate the amount of a protein in the cell A: Genes can be transcribed into mRNA with different efficiencies. B: Many ribosomes can bind to a single mRNA molecule. C: Proteins can be tagged with ubiquitin, marking them for degradation. D: Nuclear pore complexes can regulate the speed at which newly synthesized proteins are exported from the nucleus into the cytoplasm.
