During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
During what phase do maternal and paternal homologous chromosomes pair?
Two pairs of homologous chromosomes line up and form a tetrad near the beginning of prophase I of meiosis. The tetrads then perform the crossing over and recombination process before migrating to the cell equator.
What phase of mitosis do the spindle fibers elongate?
step 1 ( prophase) step 1 ( prophase)
What is the first phase in meiosis?
Meiosis 1: Prophase 1, Metaphase1, Anaphase 1, Telophase 1. Meiosis 2: Prophase 1, Metaphase 2, Anaphase 2, Telophase 2. Makes 4 daughter cells that contain 4 chromosomes each.
Where is the tetrad formation?
prophase 1
What forms from a pair of homo logs during prophasee 1?
In prophase 1 the pair of homologous Chromosomes come together to form a tetravalent or bivalent, which contains four chromatids.
WHEN DO Chromosomes decondense into diffuse chromatin?
At the beginning of Prophase 1 during meiosis. It occurs in a sub-stage of Prophase 1 called Leptonema.
During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
At the beginning of prophase 1 there are how many molecules of DNA in a developing sperm cell?
Question:At the beginning of prophase I there are ________ molecules of DNA in a developing human sperm cell.Your Answer:2392CORRECT ANSWER46INCORRECThalf as many (as compared to somatic cell)twice as many (as compared to mature sperm)
Number of cells during prophase?
There is still only 1 cell during prophase.
During what phase do maternal and paternal homologous chromosomes pair?
Two pairs of homologous chromosomes line up and form a tetrad near the beginning of prophase I of meiosis. The tetrads then perform the crossing over and recombination process before migrating to the cell equator.
What is the pairing of homologous chromosomes called?
The pairing of homologous chromosomes during prophase 1 is called crossing over. The chromosomes make a copy of themselves. The 4 cells can now twist together and exchange pieces.
What phase of mitosis do the spindle fibers elongate?
step 1 ( prophase) step 1 ( prophase)
When does the nuclear membrane dissolve in mitosis?
Hello :) Nuclear membrane breaks right before metaphase 1 which is Prophase 1 thank U
What is the first phase in meiosis?
Meiosis 1: Prophase 1, Metaphase1, Anaphase 1, Telophase 1. Meiosis 2: Prophase 1, Metaphase 2, Anaphase 2, Telophase 2. Makes 4 daughter cells that contain 4 chromosomes each.
What phase of mitosis does the nuclear envelope and the nucleus disappear and a spindle forms?
telophase II No, not Telophase. Took the test, chose prophase, was correct.
What is the correct order for the sequence of meiosis?
Interphase Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Cytokinesis 1 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 Cytokinesis 2
