In Somatic Cell Gene Therapy, What Type Of Vector Is Most Commonly Used To Alter A Specific
Set Of An Individual's Somatic Cells?
A.
Virus
B.
Bacteria
C.
RNA Polymerase
D.
Recombinant DNA
CORRECT ANS>>A
In Somatic Cell Gene Therapy, A Vector Is Used To Carry A Normal Copy Of The Mutated Gene
Into The Individual's Cells. These Vectors Are Usually Viruses, Such As Retroviruses, Lentiviruses,
Or Adenoviruses, Which Have Been Genetically Modified So That They Contain The Normal
Human Gene And Cannot Make Copies Of Themselves (Otherwise They Could Cause A Viral
Infection). Bacteria, RNA Polymerase, And Recombinant DNA Are Not Used As Vectors In
Somatic Cell Gene Therapy.
In DNA Replication, What Does The Enzyme DNA Polymerase Do?
A.
Travel Along The Single DNA Strand, Adding The Correct Nucleotide To The New Strand
B.
, Move Along The Double Strand Of DNA To Unwind The Nucleotides Of The Double Helix
C.
Hold The Double Strand Apart While The Correct Nucleotides Are Added To The Strand
D.
Transport The Double Strand Of DNA From The Nucleus To The Cytoplasm For Protein Formation
CORRECT ANS>>A
The DNA Polymerase Enzyme Travels Along The Single DNA Strand, Adding The Correct
Nucleotides To The Free End Of The New Strand (See Figure 4-3, B). The Correct Option Is The
Only One That Accurately Describes The Process Involved In DNA Replication Using DNA
Polymerase.
How Is Transcription Best Defined?
A.
DNA Polymerase Binds To The Promoter Site On Ribonucleic Acid (RNA).
B.
RNA Directs The Synthesis Of Polypeptides For Protein Synthesis.
C.
RNA Is Synthesized From A DNA Template.
D.
A Base Pair Substitution Results In A Mutation Of The Amino Acid Sequence.
CORRECT ANS>>C
Transcription Is The Process By Which RNA Is Synthesized From A DNA Template. The Correct
Option Is The Only One That Accurately Defines The Term Transcription.
