BIOL110 EXAM QUESTIONS AND
ANSWERS
Cell - Correct Answers -Membrane-bound structures that occur as functional
independent units of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.),
or as structural or fundamental units in a biological tissue specialized to perform a
particular function in multicellular organisms (e.g. plants and animals).
Unicellular - Correct Answers -adjective
(1) Having or consisting of only one cell.
(2) Pertaining to an organism whose functions are all carried out within one cell.
Multicellular - Correct Answers -adjective
Having or consisting of many cells or more than one cell to perform all vital functions.
Cell differentiation - Correct Answers -noun
The normal process by which a less specialized cell develops or matures to possess a
more distinct form and function.
Metabolism - Correct Answers -noun
The process involving a set of chemical reactions that modifies a molecule into another
for storage, or for immediate use in another reaction or as a by product.
Monomer - Correct Answers -(1) A molecule that may react chemically to another
molecule of the same type to form a larger molecule, such as dimer, trimer, tetramer,
polymer, etc.
(2) The simplest unit, or the repeating unit, of a polymer.
Macromolecule - Correct Answers -A large complex molecule, such as nucleic acids,
proteins, carbohydrates, and lipids, with relatively large molecular weight.
, Monomer (plural) - Correct Answers -Monomers
Enzyme - Correct Answers -
Macromolecule (plural) - Correct Answers -Macromolecules
Protein - Correct Answers -(biochemistry)
A molecule composed of polymers of amino acids joined together by peptide bonds. It
can be distinguished from fats and carbohydrates by containing nitrogen. Other
components include carbon, hydrogen, oxygen, sulphur, and sometimes phosphorus.
Gene - Correct Answers -(cell and molecular biology)
The fundamental, physical, and functional unit of heredity.
Protein (plural) - Correct Answers -Proteins
DNA - Correct Answers -noun
A double-stranded nucleic acid that contains the genetic information for cell growth,
division, and function.
Gene (plural) - Correct Answers -Genes
Mutation - Correct Answers -(general)
A change in or the process of changing, e.g. nature, form or quality.
(genetics)
(1) A permanent, heritable change in the nucleotide sequence in a gene or a
chromosome; the process in which such a change occurs in a gene or in a
chromosome.
(2) A mutant, or an individual exhibiting such a change.
Reproduction - Correct Answers -The production of offspring by organised bodies.
Origin: L. Re = again, productio = production
Mutation (plural) - Correct Answers -Mutations
