E 1. chromatin a. Study of the nature of diseases, their causes, development,
and consequences
B 2. chromosome b. Molecule that holds genetic information capable of
replicating and producing an exact copy whenever the cell
divides
G 3. cytoplasm c. Cellular structure that provides a specialized function, such
as the nucleus (reproduction), ribosomes (protein synthesis),
Golgi apparatus (removal of material from the cell), and
lysosomes (digestion)

acid (DNA) acids and proteins
F 5. metabolism e. Threadlike structures within the nucleus composed of a
deoxyribonucleic acid (DNA) molecule that carries hereditary
information encoded in genes
C 6. organelle f. Sum of all physical and chemical changes that take place in
a cell or an organism
A 7. pathology g. Jellylike substance found within the cell membrane
composed of proteins, salts, water, dissolved gases, and
nutrients
B. The Cell Cycle
Each cell in a multicellular organism receives information from different sources and processes
and this information will decide what this cell will become. The image below is the representation
of the whole cell cycle:
