Cell Division
This type of cellular reproduction requires the fusion of gametes.
What is SEXUAL REPRODUCTION?
This phase marks the final stage of cell division and occurs simultaneously with telophase.
What is CYTOKINESIS?
Crossing over occurs during this phase.
What is PROPHASE I?
While independent assortment and random fertilization shuffle genes at the whole chromosome level, individual genes can be shuffled during meiosis through this.
What is CROSSING OVER?
The lower order of DNA organization and its associated proteins.
Asexual reproduction results in the formation of these.
What are CLONES?
In this phase, chromatin becomes tightly coiled, chromosomes join to become sister chromatids, and the mitotic spindle forms from centrosomes.
What is PROPHASE?
While there are sister chromatids in both types of eukaryotic cell division, meiosis contains these as it begins as a 2n cell.
What are TETRADS?
Down syndrome is caused by an extra chromosome, also known as this.
What is TRISOMY 21?
These are the three sub-phases in interphase.
What are G1, S phase, and G2?
Eukaryotic cells undergo these two types of cell division; one sexual, and one asexual.
What are MEIOSIS and MITOSIS?
This is the "growing phase", where the cell replicates its DNA and duplicates organelles.
What is INTERPHASE?
Tetrads align at the cell's equator side by side, where homologous chromosomes are held together at sites of crossing over during this.
What is METAPHASE I?
Because of this, the orientation of tetrads is random and there are two equally probable arrangements of chromosomes during metaphase I.
What is INDEPENDENT ASSORTMENT?
What is a CLEAVAGE FURROW?
Prokaryotes divide using this specific type of cellular reproduction.
What is BINARY FISSION?
In this phase, motor proteins attached to the kinetochore proteins walk chromosomes toward opposite ends of the cell.
What is ANAPHASE?
Two haploid daughter cells are formed during this latter phase after chromosomes arrive at the poles of the cell during this former phase.
What are CYTOKINESIS and TELOPHASE I?
This accident resulting in chromosome pairs failing to separate can occur during either meiosis stage.
What is NONDISJUNCTION?
Meiosis II is often described as being extremely similar to this.
What is MITOSIS?
These are the three major steps of binary fission.
What are CHROMOSOME DUPLICATION, CELL ELONGATION, and CELL WALL CREATION (then division)?
During this phase, sister chromatids line up at the cell's "equator" and kinetochores link to microtubules from opposite poles.
What is METAPHASE?
During this phase, the tetrads separate and move to opposite poles, but sister chromatids remain attached and migrate to the poles of the cell.
What is ANAPHASE I?
What is POLYPLOID?
Mitosis results in these cells and meiosis results in these.
What are TWO HAPLOID DAUGHTER CELLS and FOUR HAPLOID DAUGHTER CELLS?
