Chapter 1 Study Of Life Flashcards
Genome
All the genetic instructions an organism inherits
Emergent properties
Interactions among components at each level of biological organization
Gene expression
The process by which a gene’s information is converted into a protein or an RNA product
Prokaryotic cell
Unique to bacteria and archaea, lacks both a nucleus to enclose its DNA and cytoplasmic organelles
Eukaryotic cell
With a nucleus containing DNA, and numerous membrane bound organelles, is typical of all other living things
Negative feedback
End product slows down a process, often by inhibiting an enzyme early in a chemical pathway
Positive feedback
End product speeds up its production
Light energy
The main source of energy for producers in an ecosystem
Taxonomy
Branch of biology concerned with the naming and classifying of organisms
Polar covalent bond
Results from an unequal sharing of electrons between atoms
What is the cation of NH4CI
NH4 with a charge of +1
Hydrogen bond
The slight negative charge at one end of one water molecule is attracted to the slight positive charge of another water molecule
Reductionism
Reduction of complex systems to simpler components that are more manageable to study
Systems biology
Constructs models for dynamic behavior of whole biological systems
