Briefly, describe one mode of post-translational modification that occurs once translation is finished.
Consider this list (below) of steps involved in transcription. These steps are out of order.
TRANSCRIPTION:
1. mRNA travels through a nuclear pore and enters the cytoplasm
2. the mRNA polymerase attaches at the start of a specific gene
3. RNA polymerase reads the gene surface4. a transcription factor bonds to a promoter site5. DNA molecule is unwound
6. a complimentary mRNA is produced
What is the correct order of this transcription?
Consider the Rho-dependent terminator sequence
5’CCCAGCCCGCCUAAUGAGCGGCCUUUUUUUU-3’. What affect would a point mutation at any one of the bolded and underlined nucleotides disrupt termination of transcription?
Group of answer choices
Mutation in one of these nucleotides would disrupt base pairing, preventing the formation of the hairpin and disrupting termination.
Mutation in one of these nucleotides would have no affect on base pairing, so the termination hairpin is formed and termination proceeds.
Mutation in one of these nucleotides would not disrupt base pairing, but would prevent the formation of the hairpin and disrupt termination.
Mutation in one of these nucleotides would disrupt base pairing, but not affect the formation of the hairpin and termination proceeds.

- Choose any/all that apply to mRNA processing in eukaryotes. The "starter/initiator" methionine codon is added to the 5' end of each mRNA molecule during post-transcriptional processing. The entirety of every mRNA transcript is always translated to protein. The 5' m'G cap interacts with the 3' poly (A) tail (via initiation factors and other proteins) to circularize an mRNA as part of the initiation of protein translation. mRNA processing occurs while genes are actively being transcribed.arrow_forwardTranscription of a typical gene encoding a polypeptide in eukaryotes involves all of the following EXCEPT: transcription of DNA corresponding to both introns and exons. transcription of the DNA corresponding to the gene of the polypeptide which may include UTRS (c) RNA synthesis by RNA polymerase II. the splicing together of a number of exons in the DNA prior to transcription.arrow_forwardTranscription is currently believed to occur in bursts, whereby increased burst frequency is associated with increased promoter strength and RNA synthesis. What is the evidence that this is occurs in cells? Describe in a stepwise detail how phase separation and condensates might contribute to the bursting phenomenon.arrow_forward
- Define both transcription and translation. In addition, describe the role(s) of each of the following in the processes of gene expression and protein synthesis: DNA, mRNA, tRNA, rRNA, ribosome(s), RNA polymerase, codon, anticodon, amino acid(s) and polypeptide(s). Be detailed in your answer.arrow_forwardBriefly discuss (referring to the images provided) why mutant 2 fails to produce functional protein. Note that none of the mRNA transcribed from this gene is of the expected size; some of the mRNA molecules produced are 223 nucleotides shorter than expected, whilst others are 47 nucleotides longer than expected.arrow_forwardFor each of the five short mRNA nucleotide sequences given in the table below: 3. Translate the original sequence (for these short sequences start translation at the first nucleotide) 4. Identify (and highlight or underline) the one nucleotide difference between the original (left) and altered (right) sequences 5. For each altered nucleotide sequence give the type of mutation (effect at the DNA/nucleotide level; see #1 above) 6. Translate each changed sequence. Does the mutation result in a change in the amino acid sequence? If so, what is the effect of the mutation on protein structure (amino acid sequence; see #2 above)arrow_forward
- Describe the initiation step of bacterial transcription (make sure to include important enzymes, parts, and sequences in your answer) up to the beginning of elongation. What are three ways that transcription differs between bacteria and eukaryotes? (I'm not looking for types of RNA modification, just in terms of transcription)arrow_forwardExplain the process of transcription in eukaryotic systems by considering the CDK9 gene (search more information about the function of CDK9 in relation to RNA polymerase II). If CDK9 is an example of a gene to be transcribed, explain from initiation, elongation, to termination with proteins involved, by including the important general transcription factors, mention which RNA polymerase.arrow_forwardDiscuss the process of eukaryotic transcription in detail and mention the specific enzyme needed in each stage.arrow_forward
- One fundamental difference between transcription in prokaryotes and eukaryotes is: eukaryotic RNA transcripts undergo polyadenylation (poly-A tail; cap) eukaryotes produce single RNA transcripts called operons that code for several proteins prokaryotes undergo capping of their 5' end of the RNA transcript prokayotic transcription occurs in the nucleus O prokaryotes have intervening sequences that are spliced during processing of the RNA transcriptarrow_forwardConsider the Rho-dependent terminator sequence 5’CCCAGCCCGCCUAAUGAGCGGCCUUUUUUUU-3’.

Define transcription and translation. How does transcription and translation differ in prokaryotes vs. eukaryotes (i.e. What is present in one but not the other)? 2.) What it means when we say that genetic code is redundant? 3.) Describe the stages of transcription (in detail for each step) - what components are required? 4.) Describe the stages of translation in eukaryotes (initiation, elongation, termination)arrow_forward
