Gene Reg & Express
This molecule carries the genetic instructions from DNA in the nucleus to the ribosome for protein synthesis.
What is mRNA?
This is the process by which organisms better adapted to their environment tend to survive and produce more offspring.
What is natural selection?
This term refers to all the living and nonliving components of a particular environment.
The process by which DNA is converted into a complementary RNA sequence is called this.
What is transcription?
The type of selection that favors the average phenotype and reduces variation.
What is stabilizing selection?
The maximum population size that an environment can sustain is known as this.
What is carrying capacity?
In prokaryotes, this operon is an example of an inducible system that is usually off but can be turned on in the presence of lactose.
What is the lac operon?
This principle explains that individuals do not evolve but ____ do.
This model describes how populations grow when resources are unlimited.
What is exponential growth?
Eukaryotic gene expression is regulated by proteins that bind to these non-coding regions of DNA, which can be located far from the gene regulate.
What are enhancers?
This is the term for when a natural disaster drastically reduces a population's size and genetic diversity.
What is a bottleneck event?
This type of interspecific interaction benefits one species while the other is unaffected.
What is commensalism?
This RNA-based mechanism silences gene expression by degrading mRNA or blocking its translation, and plays a role in post-transcriptional regulation.
What is RNA inference (RNAi)?
This type of selection favors both extreme phenotypes at the expense of intermediate ones, possibly leading to speciation.
What is disruptive selection?
This term describes the succession that occurs in an area where no previous community existed, such as after a volcanic eruption.
What is primary succession?
