Genetics code for what?
What is the form of DNA?
In the form of DNA, the 2 strands of DNA are what?
Anti-parallel and semi-conservative
Who came up with the discovery of the form of DNA? Also how d
Decomposition Ecology 1-24
The Black Box of Decomposition
Decomposition: breakdown of organic matter into simpler inorganic forms and the
associated release of energy
o Organic matter + Electron acceptor = energy
Role of Decomposition in Carbon Cycle
BIOL 3060 Ecology
Grew out of taxonomy, natural history
Ernst Haeckel: coined term Oikos
o Oikos: Greek for house
o Father of modern ecology
Ecology: scientific study of interactions between organisms and their environment
Example of applied ecology job
o Conservation Biologist
Scientific Method an ecologists most important tool
Modern ecology grew out of taxonomy and natural history disciplines

in aerobic respiration, oxygen can be replaced with.
what is the sum of all chemical reactions in a cell?
the break DOWN of glucose for energy
in the lag phase.
-intense activity; preparation
-BUT no actual increase in population
-adapting to conditions
in the log phase.
-exponential increase in population
-fastest growth occurs*
the stationary phase is the.
can proteins be nutrients?
no- they are too big!
some amino acids can be.
a final electron acceptor*
does oxygen participate in our metabolism?
how do we mea
what are viroids?
-*lack protein coat = not a virus
-potato spindle-tuber disease (hepatitis-D)
a prion is.
-a protein with a mutation in it
(but almost identical to normal protein)
why can't prions be stopped?
where do viruses carry out activities?
within living cells
are viruses living?
the only purpose of viruses is.
why are viruses not living?
-can only replicate inside host cell
Do all viruses go through a latent phase?
What is the Varicella-Zoster virus?
The virus connected to shingles in adults and chicken pox in children

What is HIV a
What is the backbone of the nucleic acid monomer? What role do nitrogenous bases
play in nucleic acids?
Sugar and phosphate; They stick off the sides, perpendicular to the backbone and pair
with their complementary base in an o
When tumor suppressor genes are inactivated by mutations what can happen:
cancer MAY occur
-(similar to Oncogene)-Oncogene causes cells to divide excessively
(blank) is a photographic inventory of and individual's chromosomes
Mutations are changes in the DNA base sequence that may be caused by:
A DNA error
Mutagen-(causes genetic change)
(BLANK) normally give rise to only limited range of cell types
Adult stem cells
can sexually active females b
What is a mutation where you have either a deletion or insertion?
What mutations occur naturally? Induced by physical or physical agent? Change in
genotype, but not phenotype?

Ex. Harold is a grandfather. Harold is bald. Therefore, grandfathers are bald
Ex. All men are mortal. Harold is a man, Therefore, Harold is mortal
Ex. Next number in sequence 6, 13, 20, 27
