Molecular Biology Exam questions
and answers graded A+
Cells are - ANS✅✅Basic unit of life
Eukaryotes - ANS✅✅Cells that enclose their DNA in nuclei
Prokaryote - ANS✅✅unicellular organism that lacks a nucleus
Cells can vary in - ANS✅✅shape, Function and size
Cells can move because of - ANS✅✅Cilia, Flagella
What 3 things do all cells have in common? - ANS✅✅plasma membrane, cytoplasm, Central
dogma
plasma membrane - ANS✅✅A selectively-permeable phospholipid bilayer forming the boundary of
the cells
Cytoplasm - ANS✅✅A jellylike fluid inside the cell in which the organelles are suspended
Central Dogma - ANS✅✅DNA -> RNA -> Protein
Genes - ANS✅✅DNA segments that serve as the key functional units in hereditary transmission.
Robert Hooke - ANS✅✅first to observe "small chambers" in cork and call them cells.
microscope - ANS✅✅An instrument that makes small objects look larger
True or False: There are 3 domains of life - ANS✅✅True
, What is the definition of a cell? - ANS✅✅Membrane-enclosed unit filled with aqueous solution
that can replicate on its own
What is common to All cells? - ANS✅✅Central Dogma of Molecular Biology
Prokaryotic cells are - ANS✅✅the simplest type of cells
Prokaryotes are mostly - ANS✅✅bacteria
Prokaryotes are very - ANS✅✅abundant and diverse
Prokaryotic cells dominated the earth prior to the atmosphere becoming rich in oxygen? -
ANS✅✅True
Cyanobacteria - ANS✅✅Bacteria that can carry out photosynthesis
Prokaryotes are divided into two separate domains - ANS✅✅Eubacteria and Archaea
Archaea - ANS✅✅Domain of unicellular prokaryotes that have cell walls that do not contain
peptidoglycan
What evolved the metabolic use of oxygen? - ANS✅✅prokaryotes
Aerobic - ANS✅✅Process that requires oxygen
Anaerobic - ANS✅✅Process that does not require oxygen
The Endosymbiotic Theory - ANS✅✅theory that eukaryotic cells formed from a symbiosis among
several different prokaryotic organisms
genome fusion - ANS✅✅fusion of two prokaryotic genomes, presumably by endosymbiosis
