What else can I help you with?
Part of the cell that holds the chromosomes?
part of cell that contains the chromosomes
Doubled chromosomes first become visile in which step of mitosis?
double chromosomes first become visible in which step of mitosis?
Why are chromosomes called doubles chromosomes just before mitosis begins?
Amount of DNA that has been doubled
In what stage of mitosis do the centromeres hold the doubled chromosomes together?
Prophase
What is the first stage of mitosis where the chromosomes become shortened and doubled?
Prophase
What cell part is doubled or duplicated or copied at the end of interphase?
The chromosomes are copied.
What structure in a cell nucleus holds hereditary information?
chromosomes
In mitosis or meiosis do doubled chromosomes pair to form tetrads?
In meiosis, doubled chromosomes (homologous pairs) pair to form tetrads during prophase I. This allows for genetic recombination to occur between homologous chromosomes. In mitosis, chromosomes do not pair to form tetrads as there is no crossing over between homologous chromosomes.
What is the doubled rod of condenced chromatin?
the answer is CHROMOSOME your very welcome
Why is it necessary for meiosis to produce cell with half the number of chromosomes?
To conserve the chromosomal number. Otherwise it will doubled
How does tetrad form in prophase I of meiosis?
In prophase I, doubled homologous chromosomes group together to form a tetrad.
Doubled rod of condensed chromatin?
The doubled rod of condensed chromatin is known as a chromosome. Chromosomes are tightly packed structures of DNA and protein that contain the genetic information of an organism. During cell division, chromosomes condense further to facilitate separation and distribution of genetic material to daughter cells.
