Molecular biology exam test quizzes
and answers graded A+
Organism - ANS✅✅is any contiguous living system, such as an animal, plant or bacterium. All
known types of organisms are capable of some degree of response to stimuli, reproduction, growth
and development and homeostasis.
Cell - ANS✅✅The smallest structural and functional unit of all living organisms
prokaryotic cells - ANS✅✅Are unicellular. They are either bacteria or archaea. cell lacking a true
membrane-bound nucleus.
ex.Bacteria are prokaryotic cells.
eukaryotic cells and 4 eukaryotic kingdoms - ANS✅✅a cell with a true nucleus; a cell with a nuclear
membrane and organelles
1.Protista,
2. Fungi,
3. Plantae
4. Animalia.
all taxonomy levels from domain to species - ANS✅✅Domain, Kingdom, phylum, class, order,
family, genus, species
scientific method and how its used - ANS✅✅method of research in which a problem is identified,
relevant data are gathered, a hypothesis is formulated from these data, and the hypothesis is
empirically tested:
observation
hypothesis
experiment
conclusion
, genomes/ genomics - ANS✅✅Genomes-entire set of genetic information that an organism carries
in its DNA
Genomics- study of genomes ( genes and their functions)
proteomes/proteomics - ANS✅✅proteomes-Protein product of gene translation
proteomics-comprehensive high-throughput analysis of proteomes using state of the art tools
-concept is to gain insight into the fxn of biological systems by studying all proteins in a cell rather
than each individually
Cell theory (who & what )
Names and dates of scientists involved in the cell theory - ANS✅✅All cells come from pre-existing
cells and have certain processes, molecules, and structures in common . the cell is the basic unit of
structure and function of all living things . cells have DNA.
"omnis cellula e cellua" = all cells come from other cells
Schleiden & Schwann 1838/39
cell biology - ANS✅✅the branch of biology dealing with the study of cells, especially their
formation, structure, components, and function.
molecular biology - ANS✅✅the branch of biology that deals with the nature of biological
phenomena at the molecular level through the study of DNA and RNA, proteins, and other
macromolecules involved in genetic information and cell function, characteristically making use of
advanced tools and techniques of separation, manipulation, imaging, and analysis.
differences and example of discovery based science and manipulative science - ANS✅✅discovery
science- discovering by observation , not controlling anything ex. observing what deer like to eat by
watching them without any interference.
manipulative science- controlled observation. ex. putting chemicals such as pesticides in the soil to
see how the plants around it react and what happens.
