What else can I help you with?
What distinguishes prophase 1 of meiosis from prophase of mitosis?
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
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.
What is the land forms and water forms of Lincoln city?
it forms like this along timeago the world was nothing but a big sea
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What is Tightly coiled form of DNA called?
Coiled up DNA, combined with protein histone, forms chromosomes.
What structure forms in prophase along which the chromosomes called?
The answer is Spindle Fibers.
What structure forms in prophase along with the chromosomes move?
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
Which structure forms in prophase along which the chomosomes move?
spindle fiber
What forms during prophase to Later attach move chromosomes?
Spindle fibers
During what cell cycle phase is the spindle formed?
The spindle is formed during the prophase stage of mitosis or meiosis. In prophase, microtubules organize into a structure called the spindle apparatus, which helps separate the chromosomes during cell division.
What are the 4 parts of mitosis and what happens to the chromosomes in each?
the four parts of mitosis are prophase,metaphase, anaphase, and telophasein prophase, the nuclear envelope breaks down and a spindle forms between to centrioles. in metaphase,the chromosomes align along the equator of the cell.in anaphase, the chromatids (duplicated chromosomes) are seperated.in telophase,the two cells begin to pull apart, but with plant cells, a cell wall is built in between the two cells.
What three things happen in the prophase?
The DNA replicates itself and forms chromosomes to prepare for the breaking apart of the nuclear membrane.
How one division of the nucleus a new spindle forms around each group of chromosomes?
telophase
What is the composition of a tetrad at the beginning of prophase you?
One pair of homologous chromosomes. One chromosome in a tetrad is paternally inherited, while the other is maternally inherited. Each chromosome consists of two chromatids.
What phase of mitosis does the nuclear envelope and the nucleus disappear and a spindle forms?
The phase of mitosis where the nuclear envelope and nucleus disappear is called prophase. During prophase, the chromatin condenses into discrete chromosomes, and the spindle apparatus begins to form, facilitating the movement of chromosomes during cell division.
When DNA becomes compacted it forms the structure?
In the very first step of mitosis, the prophase.
What distinguishes prophase 1 of meiosis from prophase of mitosis?
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
