Exam 2 Flashcards
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Chromosome
a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
DNA
deoxyribonucleic acid
a very strong reason for acting in a certain way, for example, to protect your money, power, or reputation
vested Interest
of a species, family, or other larger group) having no living members
Extinct
is the most recent population of organisms from which all organisms now living on Earth have a common descent.
LUCA Last universal common ancestor
a distinguishing quality or characteristic, typically one belonging to a person. genetically determined
trait
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
evolution
still in existence; surviving.
Extant
showing the evolutionary relationships among various biological species or other entities—their phylogeny —based upon similarities and differences in their physical or genetic characteristics.
Phylogenetic Tree
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
Gamete
a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Gene
does not obtain its energy from the sun. It gets its energy by consuming plant or animal matter
Heterotrophic
explains how eukaryotic cells may have evolved from prokaryotic cells. Basically, this means that once upon a time, there were three prokaryotic cells: one that was capable of aerobic respiration and converting energy, one that was capable of photosynthesis and one that was incapable of doing either of these processes. The lazy cell that was incapable of doing respiration and photosynthesis engulfed - or ate - the other cells.
Endosymbiotic Theory
4 DNA components
Encoding Information, Gene expression, replication, mutation/recombonation
practical applications of trees
medical, conservation, criminal justice, phylogeny
Science Literacy points
Science is a collaborative process
Science is not static
Some science sources have more of a vested interest than others
applied science is not only for professional scientists
