EBIO 1210 Exam 3 Mastering Questions
With Correct Answers

Where |is |a |bacterial |cell's |DNA |found?

A.ribosomes |

B. |nucleus |

C. |peroxisome |

D. |nucleoid |region |

E. |capsule |- |CORRECT |ANSWER✔✔-D



Bacteria |lack |a |nucleus; |their |DNA |is |found |in |the |nucleoid |region.



The |structure |that |regulates |the |passage |of |material |into |and |out |of |this |bacterial |cell |is |
indicated |by |the |letter |_____. |(refer |to |picture |1)

A

B

C

D

E |- |CORRECT |ANSWER✔✔-C



The |plasma |membrane |is |selectively |permeable



Find |the |feature |NOT |shared |by |all |domains |of |life. |First |exclude |the |four |features |shared |by |
all |domains.

,A. |production |of |ATP

B. |phospholipid |bilayers

C. |DNA

D. |protein |synthesis |on |rough |ER

E. |protein |synthesis |on |ribosomes |- |CORRECT |ANSWER✔✔-D



Explanation: |Prokaryotes |do |not |have |a |membrane |around |their |nucleus |or |an |endomembrane
|system |and |therefore |do |not |have |rough |ER. |They |synthesize |their |proteins |using |free |


ribosomes.

C. |Eukaryotes |acquired |their |mitochondria |by |engulfing |other |eukaryotes.

D. |Prokaryotes |are |eukaryotes |that |ejected |their |mitochondria.

E. |Eukaryotes |acquired |mitochondria |and |chloroplasts |by |engulfing |prokaryotes. |- |CORRECT |
