Essential cell biology

What would be the most obvious outcome of repeated cell cycles consisting of S phase and M phase only? (a) Cells would not be able to replicate their DNA. (b) The mitotic spindle could not assemble. (c) Cells would get larger and larger. (d) The cells produced would get smaller and smaller. - -d...

archaea - -One of the two divisions of prokaryote, often found in hostile environments such as hot springs or concentrated brine. -bacteria - -Commonly used name for any prokaryotic organism, but more precisely refers to the eubacteria, the "true bacteria," one of the three major domains of lif...

Restriction endonuclease - -cleaves DNA molecules at a specific sequence of bases à molecular scissors, Laboratory tools, wide spectrum of application. They have sticky and blunt ends. -Enzymes Used in DNA Technology - -I. Restriction endonuclease -cleaves DNA molecules at a specific sequence o...

Cells - -The basic unit from which a living organism is made; consists of an aqueous solution of organic molecules enclosed by a membrane. -Cell Biology - -The study of cells and their structure, function and behavior. -Cilium (cilia) - -Hairlike structure made of microtubules found on the sur...

Genes are: - -the info carrying elements that determine the characteristics of a species as a whole and of the individuals within it -Important discovery in the 1940's: - -1) simple fungi contain genetic information consisting primarily of instructions for making proteins 2) DNA is the carrier ...

acid - -In the context of cell biology, an organic molecule that dissociates in water to generate hydronium (H3O+) ions (thereby producing a low pH). It donates a protein to a water moelcule (dissociates). -amino acid - -Organic molecule containing both an amino group and a carboxyl group. α-Ami...

What is the function of proteins? - -They serve as building blocks for cell structures; they regulate of genes; and they enable cells to move and communicate with one another. -What is the likely carrier of genetic information? - -DNA -The structure of DNA was determined by who? - -James Watso...

Plasma membrane - -A protein studded, fatty film so thin that it cannot be seen with a light microscope, consisting of two-ply sheet of lipid molecules 5 nm thick which proteins have been inserted. -Lipid Bilayer - -double-layered sheet that forms the core of nearly all cell membranes -Phospha...

DNA --->RNA--->Protein - -In all living things, genetic information flows from __________ to _________ to ___________. -Robert Hooke - -By the 17th century, lenses were powerful enough to make out details invisible to the naked eye. Using an instrument equipped with such a lens, ___________...

Cell Respiration - -Process by which cells harvest the energy stored in food molecules; usually accompanied by the uptake to O2 and the release of CO2. -Oxidative Phosphorylation - -Process in bacteria and mitochondria in which ATP formation is driven by the transfer of electrons from food molecu...
