Fill in the following chart with important factors and sequences required for pol I transcription. Then complete the chart as if there was a mutation in that factor or sequence.
|
Factor or Sequence |
Describe the consequences |
Universal or gene specific |
What would the RNA look like? |
Why? |
|
UCE |
UBF1 unable to bind |
Gene specific |
Same but lower levels |
Only basal transcription would occur |
Homework Answers
| TIF-IB | DIfficulty for SL1 in binding to the sequence | Universal | lower level | Only basal transcription would occur |
| HMG-boxes | The UCE and the core elements do not come into contact. | Universal | lower levels | basal transcription |
| SL1 | SL1 is unable to bind to the promoter | gene specific | lower levels | basal transcription |
| TTF-I | Unable to terminate correctly | universal | higher levels | Transcription continues as termination is hindered |
| RRN3 | Unable to initiate specifically | gene specific | lower levels | basal transcription |

Classify each statement according to whether it applies to general transcription factors only, specific transcription factors only, both, or neither These transcription factors are found in both prokaryotes and eukaryotes. These transcription factors are proteins. These transcription factors form part of the transcription complex. One of these transcription factors binds directly to the TATA box in the core promoter. These transcription factors bind to the operator. These transcription factors bind to enhancer sequences that may be distant from the promoter....

What is the role of the transcription factors? A mutation exists in transcription factors that causes them to bind slightly downstream of the TATA box, causing them to cover the first 3 nucleotides of a gene. RNA polymerase can still transcribe the gene to mRNA, but it misses the first 3 nucleotides. How would this impact translation? RNA is single stranded, and as such, undergoes rapid rates of mutation. How would this affect the ability of siRNAs to combat RNA...
