BIO 202 EXAM 3/WEEK 3 2025 BRADLEY UNIVERSITY
ACCURATE FALL-SPRING GRADED A+ QUESTION AND
ANSWER MICROBIOLOGY AND IMMUNOLOGY
Does conjugation use horizontal or vertical gene transfer?
Horizontal gene transfer
Conjugation includes 2 types of cells, what are they?
Donor and recipient cells
Hfr stands for...?
High frequency of recombination
What can Hfr do?
They can mediate their own transfer and mediate transfer of chromosomal genes (cell to cell)
Homology refers to what adjective?
Homologous
Homologous
Similar in DNA sequence
R-factor
When the plasmids have resistance genes
,Generalized transduction
Random "mis-pack" of chromosomal DNA during the lytic cycle
What gene does generalized transduction require?
RecA gene
Generalized transduction
What does this diagram depict?
Specialized transduction
Incorrect incision of lysogenic DNA virus w/ chromosomal DNA
Transponsons are nicknamed...
Jumping genes
Transponsons are
DNA sequences that reshuffle the "genetic deck"
Can Transponsons transfer themselves from cell to cell
No, which complicates the horizontal gene transfer process
Genetic recombination
, The breakage and reunion of the same DNA molecules
How many copies of DNA are made using polymerase chain reaction?
Billions
In the central dogma, going from DNA to DNA is called:
Replication
In the central dogma, going from DNA to RNA is called:
Transcription
In the central dogma, going from RNA to proteins is called:
Translation
Is DNA temporary or permanent?
Permanent
Where do mutations occur?
DNA
What are RNA and proteins considered to be within the central dogma?
Hardwired
