DNA and Ecology
A Coggle Diagram about Ecology (Climate, Levels of Organization, Population Ecology, Water, Carbon, Nitrogen Cycle, Biomes, Characteristics of Living Things, Types of Heterotrophs, Symbiotic Relationships, Heterotrophs/Consumer- An organism deriving its nutritional requirements from complex organic substances., Chemosynthesis- Synthesis of organic compounds by energy derived from inorganic chemical reactions., Photosynthesis- Plants turn water, carbon dioxide, and energy into glucose and oxygen., Food Web
Arrows point in the direction of the flow of energy., Food Pyramid
Biomass is greatest at the bottom of the pyramid and lowest at the top.
Only 10% of energy is passed on from each level of the pyramid, the rest is lost as heat.
Poisons and toxins accumulate in the highest levels at the top of the pyramid., Biosphere- All life on Earth and the environment., Autotrophs/Producer- An organism that is able to form nutritional organic substances from simple inorganic substances such as CO2., Succession- An ongoing process in nature.
Two types of succession:
Secondary Succession, Abiotic Factors- nonliving parts of the environment., Biotic Factors- Living parts of the environment. and Ecology- Study of interactions between organisms and their environment.) and DNA (Griffith (1928)-
Smooth Pneumococcus- Dead Mouse
Rough Pneumococcus- Living Mouse
Heat Killed Smooth Pneumococcus- Living Mouse
Heat Killed Smooth Pneumococcus and Rough Pneumococcus- Dead Mouse, Hershey and Chase (1952)-
Proteins used to inject nucleic acids into other cells.
To find out what what went into the cell, isotopes were used.
Nucleic Acid- Phosphorous 35
Protein- Sulfur 37, Chargaff-
Took picture of the top of DNA., Watson & Crick-
Found out DNA is a double helix., DNA Helicase- Unzips Genes. and DNA Polyme Rase- Adds Nucleotides.)
