What happens in prophase?
Nuclear Membrane Breaks Down Sister Chromatids Condense and Become Visible Spindle Forms --> Pulls Chromatids to middle of cell and then apart Centrioles move to the opposite ends of the cell
100
What happens in Metaphase?
Sister chromatids line up at the metaphase plate
100
What happens during Anaphase?
Sister Chromatids are pulled apart by the spindle fibers One full set of chromosomes goes to one side of the cell and the other identical set goes to the other
100
What happens in telophase?
Chromosome begin to uncoil as the nuclear membrane reassembles around them The cell begins to pinch into two new cells
100
What happens during Prophase I
replicated chromosomes condense Spindle is formed Homologous chromosomes come together to form a tetrad and cross over nuclear membrane disappears
200
What happens during Metaphase I
homologous pairs/chromosomes move to the center of the cell Independent Assortment - random arrangement of chromosomes at the metaphase plate - Source of Variation
200
What happens during Anaphase I?
Homologous pairs are pulled apart towards opposite sides of the cells The maternal and paternal sister chromatids are pulled to the ends of the cell in a random fashion Beginning of the first cell division that occurs during meiosis
200
Telophase I and Cytokinesis
This phase is marked by the chromosomes arriving at the two poles of the cell The cytoplasm then divides and the cell membrane pinches into two daughter cells Result: two cells with half the amount of genetic information
200
Brief interphase before meiosis II but no
replication
200
Prophase II
the genetic material once agains coils tightly making the chromatids visible under the microscope
300
Metaphase II
the sister chromatids (each appearing as an X) move to the center of the cell
300
Anapahse II
The fibers attached to the centromere begin pulling each sister chromatid pair toward ends of the cell
300
Telophase II
The cytoplasm then divides Cell membrane pinches into two new daughter cells process comes to a close
300
Step 1 of Transcriptin
Recognize and Bind: DNA unwinds slightly so that one strand can be read RNA polymerase (enzyme) recognizes and brings to DNA at the promoter - starts code
300
Step 2 of Transcription
Transcribe: DNA strand is read by the RNA polymerase which builds a complementary stand of mRNA
400
Step 3 of Transcription
Terminate: RNA polymerase hits a terminator sequence that stops the process
400
What is the fourth step of transcription
Editing Phase: Introns - cut out and stay IN nucleus Exons - put back together and leave the nucleus to be translated
400
Step 1 of Translation
Initiate: ribosome recognizes the start sequence of mRNA - AUG tRNA also recognizes AUG and brings the first amino acid - methionine
400
Step 3 of Translation
Termination: Ribosome hits one of 3 stop codons; this tells the translation to stop
400
Where does transcription take place
nucleus
500
Where does translation take place
ribose in cytoplasm
500
Replication 1
Unwinding - Helicase - enzyme that unwinds and unzips cytoplasm
500
Replication 2
Rebuilding - DNA polymerase - enzyme that creates complementary strand of DNA
500
Replication 3
Check - DNA polymerase checks for errors
