BIOD 171 TEST PAPER QUESTIONS AND
SOLUTIONS COMPLETE REVIEW MATERIAL
●● What is the smallest biological unit of life?
Answer: A cell
●● What are the four main types of macromolecules found in cells?
Answer: Proteins, Lipids, Nucleic Acids, Carbohydrates
●● Proteins are formed from various combinations of
Answer: Amino acids
●● There are how many known forms of amino acids
Answer: twenty
●● How many amino acids are classified as being essential amino acids?
Answer: Nine
●● Where can the two major types of nucleic acids be found in the cell?
Answer: DNA, RNA. Found in the nucleus.
●● What is the role of RNA?
,Answer: RNA , found in the nucleus is capable of leaving the nucleus.
RNA is repsponsible for deciphering the hereditary information in DNA
and uses it to synthesize proteins.
●● What is the role of DNA?
Answer: DNA, found in the nucleus contains vast amount of hereditary
inforamtion, responible for inhereitable characteristic os living
organisms.
●● Complete the following RNA strand, and indicate how many bonds
are formed for each complementary pair:
3' GGUCAUCG 5'5' CC AGC 3'
Answer: 3' GGUCAUCG 5'5' CCAGUAGC 3'There are 2 bonds formed
between A and U, and 3 bonds between G and C.
●● The plasma membrane
Answer: Restricts movement of materials in and out of the cell &
Prevents essential nutrients from escaping
●● How many carbon atoms are present in glucose?
Answer: 6
●● True of False: The genetic material within a prokaryotic cell is
contained within a membrane-enclosed region.
,Answer: False
Only eukaryotic cells contain its genetic material within a nucleus.
●● True or False: Prokaryotic cells can be subdivided into Bacteria and
Archaea.
Answer: True
●● True or False: Archaea is noted for its ability to survive under harsh
conditions.
Correct!
Answer: True
Archaea can often be found in harsh conditions such as high salt levels,
high acid conditions, high temperatures and even oxygen-poor
conditions.
●● Which of the following microorganisms are considered to be
Eukarya? Select all that apply.
Answer: Animalia, Plantae, Fungi, Protista
●● Microorganisms classified as Plantae obtain most of their energy by
converting [answer1] energy into [answer2] energy.
Answer: 1. Light (sunlight)
2. chemical (sugars)
, ●● Which of the following are considered Protista? Select all that apply.
Answer: Algae, Amoeba
●● The function of the ribosome is
Answer: Protein synthesis
●● True or False: Protista retain a unicellular classification, as they are
unable to form tissue layers.
Answer: True
●● Where are ribosomes located?
Answer: cytoplasm of prokaryotic cells and in the ER of eukaryotic
cells.
●● The combination of the cell membrane and the outer membrane is
referred to as the
Answer: Cell envelope
●● The function of the mitochondria is
Answer: To produce energy (ATP)
●● True or False. All multicellular microorganisms classified as
Animalia are autotropic.
