Ecology
This level of ecological study involves the biotic component of an ecosystem.
What is the community level?
The end result of this process is 4 haploid daughter cells.
What is meiosis?
This model enables us to understand that 50% of a daughter DNA molecule is the parental molecule.
What is the semiconservative model?
This feature is required if advantageous traits are to pass from one generation to the next in a population.
What is heritability?
In both transcription and translation, this step involves the attachment of a polymerase enzyme to promoter sequence.
What is initiation?
Questions at this level of ecological study involve the interactions of a single type of organism with one another.
What is the population level?
This term refers to an organism that has two copies of alleles for each gene.
This feature of nucleotides allows one DNA molecule to be created from another.
What is complimentary base pairing?
This species concept defines a species as any group of organisms that can interbreed to reliably produce fertile and viable offspring.
What is the biological species concept?
This aspect of DNA provides control of gene expression simply by affecting which genes are accessible.
What is DNA packaging?
This latitude receives the highest input of annual solar radiation.
What is the equator? (zero degrees.)
DNA is contained in the nucleus in this form during interphase.
What is chromatin?
These pieces of DNA are synthesized and subsequently joined due to the fact that DNA polymerase only synthesizes DNA in the 5' to 3' direction.
What are Okazaki fragments?
The fundamental unit of organisms upon which natural selection acts.
What is a population?
This step in gene expression involves modifying the language of the genetic code to the language of phenotypes.
What is translation?
This population growth model accounts for limiting factors from the environment, which impart a carrying capacity for a population.
What is this logistic growth model?
In plant cells, telophase and cytokinesis include the formation of this distinguishing structure.
What is the cell plate?
This female scientist played a monumental role in the discovery of DNA's structure, yet (unlike her male collaborators) she was not awarded the nobel prize due to an untimely death due to radiation exposure during her research.
Who is Rosalind Franklin?
This aspect of Darwin's theory of evolution by natural selection involves the changing or editing of homologous structures over evolutionary time.
What is descent with modification?
Gene expression in the process by which the ________ is changed into the ______________.
What are the genotype and the phenotype?
This type of population growth pattern is directly related to the abundance of individuals in the population.
What is density dependent population growth?
This tubular structures provide structural support and control the movement and separation of sister chromatids during mitosis.
What are spindle fibers? (or microtubules)
DNA replication happens during these processes of cell division.
What are mitosis and meiosis?
These types of reproductive barriers occur prior to the fertilization of an egg by a sperm.
What are prezygotic reproductive barriers?
This step of gene expression allows different mRNA transcripts can be created from the same template RNA due to different exons being retained.
What is alternative DNA splicing?
