Alberts Essential Cell Biology Chapter 001 Module 03 Test Quiz
Bank Q & A 2023/2024 Approved
Cells correct answers The basic unit from which a living organism is made; consists of an aqueous
solution of organic molecules enclosed by a membrane.
Cell Biology correct answers The study of cells and their structure, function and behavior.
Cilium (cilia) correct answers Hairlike structure made of microtubules found on the surface of many
eukaryotic cells; when present in large numbers, its rhythmic beating can drive the movement of fluid
over the cell surface, as in the epithelium of lungs.
DNA correct answers Double-stranded polynucleotide formed from two separate chains of covalently
linked deoxyribonucleotide units. It serves as the cell's store of genetic information that is transmitted
from generation to generation.
RNA correct answers Molecule produced by the transcription DNA; usually single-stranded , it is a
polynucleotide composed of covalently linked ribonucleotide subunits. Serves a variety of structural,
catalytic and regulatory functions as well.
Protein correct answers Polymer built from amino acids that provides cells with their shape and
structure and performs most of their activities.
Central Dogma correct answers Th principle that genetic information flows from DNA to RNA to protein.
Amino Acids correct answers Small organic molecule containing both an amino group and a carboxylic
group; it serves as the building block of proteins.
Conformation correct answers Precise, three-dimensional shape of a protein or other macromolecule,
based on the spatial location of its atoms in relation to one another.
Mutations correct answers A randomly produced, permanent change in the nucleotide sequence of
DNA.
Evolution correct answers Process of gradual modification and adaptation that occurs in living organisms
over generations.
Genome correct answers The total genetic information carried by all the chromosomes of a cell or
organism.
Microscope correct answers Instrument for viewing extremely small objects.
Light Microscope correct answers Uses a focused beam of visible light and is used to examine cells and
organelles.
Electron Microscope correct answers Instrument that illuminates a specimen using beams of electrons to
reveal and magnify the structures of very small objects, such as organelles and large molecules.
