Section 1.1 Flashcards
What is the idea that living species are descendants of ancestral species that were different from the present day ones?
Evolution
are properties that arise with each new step upward in the hierarchy of life.
Emergent properties
What types of cells have a membrane-enclosed nucleus and membrane-enclose organelles?
Eukaryotic cells
What is the use of computers, software, and mathematical models to process and integrate biological information called?
Bioinformatics
are organisms that feed on producers, other , or nonliving organic materials.
consumers
A is a nucleic acid molecule that is usually a double-stranded helix, capable of being replicated and determining the inherited structure of a cell’s proteins.
DNA (deoxyribonucleic acid)
, regulates a process by its output or end product.
Feedback regulation
What is the discrete unit of hereditary information that consists of a specific nucleotide sequence in DNA?
a gene
is the process by which information encoded in DNA directs the synthesis of proteins or in some cases RNA.
gene expression
What is the genetic material of an organism or virus?
genome
is the systematic study of whole sets of genes and their interactions within a species, as well as genome comparisons between species
genomics
A form of regulation in which accumulation of an end product of a process slows the process.
negative feedback
A form of regulation in which an end product of a process speeds up that process.
positive feedback
, is a type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles
prokaryotic cell
What is the entire set of proteins expressed by a given cell or group of cells called?
proteome
