chromatid
A replicated DNA strand formed during prophase is called a sister chromatid. Sister chromatids are two identical copies of a single chromosome that are joined at the centromere. These sister chromatids will later separate during cell division.
Prophase is when chromosomes group together and prepare for division, while in telophase two new nuclei are formed. telophase is the first step of mitosis; telophase is the fourth step (last).
The number of chromosomes in daughter cells formed by the first division is the same as the parent cell, typically 46 chromosomes in humans. This is because during the first division, chromosomes are replicated and then distributed equally between the daughter cells.
50% of Canada was created during this era. This part is called Canadian Shield.
Eggs are formed in the ovaries of female animals, where they develop and mature before being released during ovulation.
A persistent RNA-DNA hybrid is formed during transcription at a phylogenetically conserved mitochondrial DNA sequence.
A replicated DNA strand formed during prophase is called a sister chromatid. Sister chromatids are two identical copies of a single chromosome that are joined at the centromere. These sister chromatids will later separate during cell division.
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.
During Prophase
Mitosis is broken up into 4 phases, Prophase, Metophase, Anaphase, and Telophase. During these phases the DNA, which was replicated during Interphase, split and 2 new cells are formed.
Prophase 1 is the phase of meiosis ll when the homologous pairs combine. It is also when centrioles seperate, spindle fibers are formed, the nuclear envelope disappears, and the chromosomes become visible.
Synapsis and the formation of tetrads occur during the prophase I stage of meiosis. This is when homologous chromosomes pair up to form a structure called a tetrad, which allows for genetic recombination between the chromosomes.
An aster forms during the prophase stage of mitosis. Asters are composed of microtubules radiating from the centrosomes located at opposite poles of the cell. They help to organize and separate the chromosomes during cell division.
During prophase of mitosis, the number of cells remains constant. Prophase is the first stage of mitosis where the nucleus condenses and the chromosomes become visible, but the cell itself does not divide yet.
prophase
Chromosomes are composed of two chromatids during the prophase and metaphase of mitosis. The chromosomes of formed in prophase and line up in metaphase.
Sister chromatids are the chromatids that are attached at the centromere. Sister chromatids are two identical copies of a chromosome produced during DNA replication, and they remain attached until they are separated during cell division.
