QUESTIONS TYPE:
➢ Multiple Choice:
➢ True Or False:
➢ Explain Or Describe
➢ Fill In The Blank
All The Best!!
,Version Final Exam 1.
1. Short Answer.
What Is The Function Of A Ribosome?
ANS. To Bring MRNA Together With tRNA Carrying An Amino Acid.
Ribosomes Are The Site Of Protein Synthesis, Facilitating The Assembly Of Amino
Acids According To MRNA Codons.
2. Short Answer.
In What Situation Would The Nucleotide Excision Repair Mechanism Be Used?
ANS. Sometimes Entire Stretches Of The Newly Synthesized Strand May Be Erroneous.
In These Instances, The Cell Will Deploy The Nucleotide Excision Repair Mechanism.
Nucleotide Excision Repair Removes Damaged Or Incorrectly Synthesized DNA
Sections To Maintain Genome Integrity.
3. Fill-In-The-Blank:
________ Proteins Increase Transcription By Facilitating Protein-To-Protein Interactions
Or By Binding To Other Regulatory Regions. ________ Proteins Cause Gene
Transcription To Decrease Or Completely Cease.
Options:
A) Activator; Repressor
B) Repressor; Activator
C) Enhancer; Silencer
D) Polymerase; Ligase
Activators Enhance Transcription, While Repressors Inhibit It.
4. True Or False:
,If False, Explain Why The Statement Is False: Each Amino Acid Is Coded By Only 1
Triplet Sequence.
ANS. False; Each Amino Acid Can Be Coded For By More Than One Triplet Sequence.
Explanation: The Genetic Code Is Degenerate; Multiple Codons Can Code For The
Same Amino Acid.
5. Fill-In-The-Blank:
The Lagging Strand Must Be Replicated In A Series Of Fragments Called
____________.
Options:
A) Okazaki Fragments
B) Leading Fragments
C) Telomeres
D) Primers
The Lagging Strand Is Synthesized Discontinuously In Short Segments Known As
Okazaki Fragments.
6. True Or False:
If False, Explain Why The Statement Is False: Selective Degradation Is A Form Of Post-
Translation Regulation.
ANS. True
Selective Protein Degradation Regulates Protein Levels After Translation.
7. Short Answer.
What Are The Three Modifications To Pre-MRNA That Occur To Make It A Functional
MRNA?
ANS. These Modifications Include The Addition Of A (1) 5' Cap, (2) Poly-A-Tail, And
(3) RNA Splicing.
These Modifications Protect MRNA And Facilitate Translation.
, 8. Fill-In-The-Blank:
The Process By Which Genes Are Expressed That Encode For Proteins Occurs In Two
Steps Called (1) ________ And (2) ________.
Options:
A) Transcription; Translation
B) Replication; Translation
C) Transcription; Replication
D) Splicing; Translation
Transcription Produces RNA From DNA; Translation Synthesizes Protein From RNA.
9. Multiple Choice:
Which Of The Following Is Not One Of The Steps Involved In The Termination Of
Translation?
A) Release Factor Binds To Stop Codon
B) Ribosomal Subunits Dissociate
C) Ribosomal Subunit Binds To Mature MRNA
D) Polypeptide Is Released
Ribosomal Subunit Binding Initiates Translation, Not Termination.
10. True Or False:
If False, Explain Why The Statement Is False: During Elongation, Only One Polymerase
Can Actively Transcribe A Single Gene At One Time.
ANS. False; During Elongation, Several Polymerases Can Actively Transcribe A Single
Gene At One Time.
Multiple RNA Polymerases Can Transcribe The Same Gene Simultaneously.
