100
When Gregor Mendel crossed a purple-flowered pea plant with a white flowered one, he obtained more than 100 offspring, each of which bore white flowers. This cross demonstrated this basic principle of genetics.
What is the Principle of Dominance?
100
He pioneered the use of the fruit fly, Drosophila melanogaster, as a model organism for genetics.
Who was Thomas Hunt Morgan?
100
This phase of mitosis follows metaphase.
What is Anaphase?
100
These German scientists determined that both animals and plants are composed of cells.
Who were Schleiden and Schwann?
100
These are the four major classes of macromolecules.
What are lipids, carbohydrates, nucleic acids, and proteins?
200
This scientist developed a graphical method of predicting the outcome of a genetic cross.
Who was Reginald Punnett?
200
She discovered the Y chromosome.
Who was Nettie Stevens?
200
This is what happens to the nucleus of a G1 cell when it is fused with an S phase cell.
What is DNA Replication? (Or, what is the start of S-phase?)
200
These are the 3 domains of life on earth.
What are Archea (Archaebacteria), Bacteria (Eubacteria), and Eukarya (Eukaryotes)?
200
Starch is a polymer of this monosaccharide.
What is Glucose?
300
The separation of two homologous alleles during gamete formation in a diploid organism demonstrates this.
What is the Principle of Segregation?
300
A cross between a dihybrid individual and a homozygous recessive individual that produces a 9:2:2:9 ratio instead of a 1:1:1:1 ratio indicates this.
What is Gene Linkage?
300
A rise in the concentration of this cellular protein triggers mitosis.
What is Cyclin?
300
Prokaryotic cells lack this organelle, which is found in all eukaryotic cells.
What is the nucleus?
300
The R-group of this amino acid is nothing more than a hydrogen atom.
What is Glycine?
400
A dibybrid cross producing offspring in a 9:3:3:1 ratio demonstrates this.
What is the Principle of Independent Assortment?
400
He was the first person to use recombination frequencies to develop a genetic map.
Who was Alfred Sturtevant?
400
The principle of Segregation results from events in this phase of meiosis.
What is the First Meiotic Division?
400
This is the organelle responsible for producing proteins for export from the cell.
What is the Rough Endoplasmic Reticulum?
400
This is the role that R-groups play in stabilizing the alpha-helix.
What is Nothing?
500
An organism of genotype AAbbCc can produce this many combinations of alleles in its gametes.
What is two (2)?
500
This is the genotype of a green parakeet which, when crossed with a white parakeet, produces only green offspring (where B is the allele for blue pigment and C is the allele for yellow pigment).
What is BBCC?
500
Genetic recombination takes place during this phase of one of the meiotic divisions.
hat is the First Meiotic Prophase?
500
The Krebs cycle takes place inside this organelle.
What is the Mitochondrion?
500
These are the prosthetic group found in myoglobin and the metal atom contained within it.
What are heme and iron?
