This precedes both meiosis & mitosis:
What is DNA replication
100
These are formed when homologous chromosomes get together in prophase I of meiosis:
What are tetrads
100
This refers to cells that have 1 set of chromosomes:
What is HAPLOID
100
In humans, our 2n number is:
What is 46
100
An organism whose somatic cells have 74 chromosomes would produce gametes with what chromosome number?
What is 37
200
This is the phase of division where centrioles replicate and the chromatin condenses. Also, the nucleolus disappears and nuclear envelope breaks down:
What is prophase
200
This is the longest phase of any phase in meiosis:
What is prophase I
200
In humans, our n number is:
What is 23
200
This is the event that leads to the first diploid cells of a sexually reproducing organism's life:
What is fertilization
200
During this phase of meiosis, random assortment of homologous chromosomes happens:
What is metaphase I
300
During this phase of division, the chromosomes have arrived at the equator, directed there by the spindle fibers:
What is metaphase
300
This event occurs early in meiosis I and results in recombinant chromosomes:
What is crossing-over
300
These are the three phases of interphase:
What are G1, S & G2
300
This is the acronym I gave you in class to remember the steps of the cell division (mitotic) cell cycle:
What is IPMAT-C
300
These fuse in plant cells to form the new cell membrane:
What are vesicles
400
This phase of division is marked by the chromosomes arriving at the poles and new nuclei forming:
What is telophase
400
This is the second event of meiosis that contributes to genetic diversity (after crossing-over)
What is random assortment of the chromosomes during metaphase I
400
This phase of the cell cycle DOES NOT occur between meiosis I and meiosis II. Why does it not?
S phase - because if it occurred we would not reduce the chromosome number.
400
This is the phase of meiosis that results in four haploid cells:
What is Cytokinesis II
400
These replicate during prophase, and make their way to opposite ends of the cell:
What are centrioles
500
Beginning in telophase, this phase of the cell cycle separates cytoplasm by either a cleavage furrow or by forming a cell plate:
What is cytokinesis
500
This refers to cells that have 2 sets of chromosomes:
What is DIPLOID
500
During this phase of meiosis, the sister chromatids separate:
What is ANAPHASE II
500
This term refers to all the cells of your body, with the exception of your haploid gametes:
What is somatic
500
This is the number one advantage for sexually reproducing species:
What is GENETIC DIVERSITY!
