Mitosis 1
Why is Mitosis so important?
It is vital for our growth and development
What are the four main phases of Mitosis?
Prophase, Metaphase, Anaphase, Telophase
Transcription and Translation
What is Meiosis?
Meiosis is a special type of cell division during which sexually reproducing organisms creates four special cells each with a copy of the necessary chromosomes
Are the cells created though Meiosis unique?
Yes, unlike Mitosis they are
During what Mitosis phase do the chromosomes arrive at the center?
Metaphase
During which phase do Spindle Fibers begin to form?
Prophase
Why is Protein Synthesis Important?
It creates proteins to allow cells to function properly
What are the eight different stages of Meiosis?
Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II
During Meiosis do Chromosomes pair up?
Yes, they do
During what Mitosis Phase do the Centromeres split apart?
Anaphase
What is the purpose of Mitosis?
To duplicate cells in an effort to form identical copies
What are the three RNA variations which are directly involved in Protein Synthesis?
mRNA, rRNA, tRNA
When does "Crossing Over" occur?
During Prophase I
What is "Crossing Over" during Meiosis?
An exchange of genetic information by genes
During what Mitosis Phase do cells spend most of their time?
Interphase
Are cells created via the process of Mitosis identical to the "parent" cells?
Yes, they are genetically identical
What occurs during Transcription?
Stand of DNA information are scripted by the mRNA are become "blueprints" to for the next stage where they will be translated.
How many cells divisions occur during Meiosis?
Two cell divisions
When do Chromosomes line up "Single File"?
During Metaphase II
When does Mitosis occur in the Cell Cycle?
Between G1 and G2
How many chromosomes does a human cell have after telophase in mitosis is complete?
46 Chromosomes
What occurs during Translation?
The mRNA translates the information provided though Transcription into an amino acid chain, in an effort to build proteins
What is a Gene?
A DNA sequence which can be translated to signify a certain trait
What are Centromeres?
Centromeres are the part which connects and holds together the Chromosome
