Water, Nucleic Acids
Water, Nucleic Acids
This kind of bonding between water molecules is responsible for most of water’s unique properties.
What is a hydrogen bond?
This nucleic acid is hypothesized to be the first genetic material because it can store genetic information, self-replicate, and catalyze reactions.
What is RNA?
The protein coat that surrounds and protects a virus’s genetic material is called this.
What is a capsid?
This system of naming organisms was invented by Carl Linnaeus.
What is binomial nomenclature?
This type of conservation protects species within their natural habitat, often within nature reserves or national parks.
What is in-situ conservation?
This property allows water molecules to stick to each other, contributing to surface tension.
What is cohesion?
This theory states that new cells come only from pre-existing cells.
What is cell theory?
This viral origin hypothesis suggests viruses evolved from sections of DNA or RNA that escaped from cells.
What is the Escape Hypothesis?
This diagram or photo shows all of the chromosomes found in a cell.
What is a karyogram?
A single species of finch evolved into 18 different species of finches on the Galapagos Islands due to this phenomenon.
What is adaptive radiation?
Because water absorbs a lot of heat before changing temperature, it is said to have a high __________.
What is specific heat capacity?
This experiment demonstrated that organic molecules could form from inorganic substances under early Earth conditions.
What is the Miller-Urey Experiment?
This type of viral cycle results in the immediate destruction (lysis) of the host cell.
What is the lytic cycle?
This domain is known for containing extromphiles.
What is Archaea?
This type of species extinction is caused by human activities.
What is anthropogenic species extinction?
This property allows water to dissolve many substances, earning it the name “universal solvent.”
What is polarity?
The process by which early prokaryotes took in other cells that became organelles like mitochondria.
What is endosymbiosis? or What is endosymbiotic theory?
This is an abrupt major change to the HA and NA surface proteins of a virus, occurring when an organism is infected with two different strains of the virus.
What is antigenic shift?
This technique is based on the gradual accumulation of sequence differences, due to mutations, over time. It can be used to estimate when clades diverged from a common ancestor.
What is a molecular clock?
This condition results from non-disjunction, an error during meiosis (while producing gametes).
What is polyploidy?
This phenomenon enables water to move up plant xylem against gravity, combining cohesion and adhesion.
What is capillary action?
This tissue in plants contains cells that are undifferentiated cells, capable of differentiating into specialized cells, and capable of endlessly reproducing.
What is meristematic tissue?
This is the dormant genetic material of a bacteriophage (a virus that infects bacteria) after it has been integrated into the bacterial host's chromosome or exists as a plasmid.
What is a prophage?
This vestigial structure is found within human Chromosome 2, suggesting the fusion site for Chromosomes 2A and 2B.
What is a telomere/vestigial telomere?
In evolutionary biology, this term refers to one of several alternative forms of a gene that can occupy the same locus, and changes in its frequency within a population over time are what drive evolution.
What is an allele?
