100
Chromosomes condense and the spindle apparatus begins to form
What is Prophase?
100
A hereditary factor that influences a particular trait.
What is a gene?
100
Movement of ions or molecules from a region of high concentration to low concentration.
What is diffusion?
100
Chemical bond that involves the sharing of electron pairs between atoms
What is a covalent bond?
100
Calalyzes the breaking of hydrogen bonds between base pairs to open the double helix.
What is helicase?
200
Kinetochore microtubles pull sister chromatids apart.
What is Anaphase?
200
Version of a gene.
What is an Allele?
200
The tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher.
What is osmosis?
200
Chemical bonding that involves the electrostatic attraction between oppositely charged ions.
What is an ionic bond?
200
Breaks and rejoins the DNA double helix to relieve twisting forces cause by the opening of the helix.
What is topoisomerase?
300
Kinetochore microtubles move chromosomes to the middle of the cell.
What is Metaphase?
300
Having two of the same allele.
What is Homozygous?
300
Solution with high concentration of solutes.
What is hypertonic?
300
Electromagnetic attractive interaction between polar molecules, in which hydrogen is bound to a highly electronegative atom.
What is a hydrogen bond?
300
Catalyzes the synthesis of the RNA primer.
What is primase?
400
Chromosomes are pulled to opposite poles of the cell and a nuclear envelope forms around each set.
What is Telophase?
400
Having two different alleles.
What is Heterozygous?
400
Solution with low concentration of solutes.
What is hypotonic?
400
Bond in which electrons are shared between atoms of elements having a difference in electronegativity less than 0.5.
What is a nonpolar covalent bond?
400
Holds DNA polymerase in place during strand extension.
What is a sliding clamp?
500
The nuclear envelope disintegrates and kinetochore microtubles make contact with chromosomes.
What is Prometaphase?
500
An individual's observable traits.
What is Phenotype?
500
Solution having the same osmotic pressure as blood.
What is isotonic?
500
Bond between two atoms in which electrons are shared unequally.
What is a polar covalent bond?
500
Catalyzes the joining of Okazaki fragments into a continuous strand.
What is DNA ligase?
