- 3. Multiple ChoiceWhich RNA bases would pair with TACGAA in transcription?AUGCUUATGCTTGCATCCGCAUCC
- 4. Multiple Choice
How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though they look and perform completely different?
The two different cells become mutated
The proteins expressed in each cell are different
They actually have different DNA in the two types of cells.
The genome of the different cells changes
- 5. Multiple ChoiceProtein molecules around which DNA is tightly coiled in chromatinHistonesWheyCaseinHemoglobin
- 6. Multiple ChoiceWhere does transcription occur in eukaryotic cells?NucleusRibosomeCytoplasmRough E.R.
- 7. Multiple ChoiceIn eukaryotic cells, transcription cannot begin untilthe two DNA strands have completely separated and exposed the promoter.several transcription factors have bound to the promoter.the 5' caps are removed from the mRNA.the DNA introns are removed from the template.
- 8. Multiple ChoiceWhich of the follwoing best describes the significance of the TATA box in eukaryotic promoters?it is the recognition site for a specific transcription factorit sets the reading frame of the mRNAit is the recognition site for ribosomal bindingit signals the end of the nucleotide sequence of the gene
- 9. Multiple ChoiceRNA polymerase moves in which direction along the DNA?5' to 3'3' to 5' along the template strand3' to 5' along nontemplate(coding) strand5' to 3' along the template strand
- 10. Multiple ChoiceA chemical modification of DNA that does not affect the nucleotide sequence of a gene but makes that gene less likely to be expressed.methylationacetylationtranscriptiontranslation
- 11. Multiple ChoiceWhich of the following is an example of post-transcriptional control of gene expression?the addition of methyl groups to cytosine bases of DNAthe binding of transcription factors to a promoterthe removal of introns and splicing together of exonsgene amplification contributing to cancer
- 12. Multiple ChoiceThe parts of a gene that do NOT code for amino acids in a protein are calledintronsexonscodonsanticodons
- 13. Multiple ChoiceThe production of mature mRNA in eukaryotes involvescutting introns out and spicing exons togetheradding the 5' capadding the 3' poly A tailall of these are correct
- 14. Multiple ChoiceWhat is the function of the poly-A tail in mRNA?to add modified guanin to the 3' end of the mRNAto indicate the site of translational terminationto code for the binding of RNA polymerase to the DNAto help protect the mRNA from degradation by hydrolytic enzymes
- 15. Multiple ChoiceA protein that binds to the operator and blocks the RNA polymeraseregulatorrepressoractivatorcorepressor
- 16. Multiple ChoiceWhich of the following events in translation is the first to occur in eukaryotes?elongation of the polypeptidebase pairing of activated methionine-tRNA to AUG of the messenger RNAbinding of the larger ribosomal subunit to smaller ribosomal subunitsthe small subunit of the ribosome recognizing and attaching to the 5'cap
- 17. Multiple ChoiceWhat must happen to a newly made polypeptide before it can be secreted from a cell?it must be translated by a ribosome that remains free of attachment to the ERits signal sequence must target it to the ER, after which it goes to the GolgiIts signal sequence must be cleaved offIts signal sequence must target it to the plasma membrane
