Mediates the degradation of the siRNA or miRNA to repress gene expression a. I onlyb. II onlyc. I and IId. II and III
Describe the synthesis of the c-Jun protein starting with the synthesis of the protein’s mRNA (transcription has already happened so you have a transcript – do not describe transcription) Describe the details of how c-Jun pol is made and targeted to where it works. Since you are starting with mRNA, be sure to discuss how the mRNA gets to the ribosome. This question is about protein transport NOT about the function of the c-Jun protein.
Transcription of genes starts at regions of the genome called
Gene expression can be affected by all of these EXCEPT: - Considering chromosomes -Adding mote ATP -Degrading mRNA -Degrading proteins
Select the incorrect statement: O A. Transcription produces an mRNA of a gene that leaves the nucleus. O B. A hydrophobic hormone-receptor complex may increase the expression of a specific protein by stimulating the transcription of more of that protein's MRNA. OC Protein synthesis is a two-phase process that includes transcription and translation. O D, In the process of transcription, the entire chromosome is copied by RNA polymerase.
While mRNA strands are being created a sequence is sometimes miscopied. What is the best possible outcome for the cell should this take place? Top of Form The miscopied sequence codes for the same amino acids as the original sequence. The new sequence creates a protein that serves a different function from the original. The ribosomes will correct the mistake before the tRNA matches an amino acid to it. The mRNA will only be used to create non-critical proteins for the cell.
