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.
What else can I help you with?
What structure forms in metaphase?
In metaphase, the chromosomes line up along the metaphase plate in the center of the cell. Microtubules from opposite poles of the cell attach to the centromere of each chromosome to help align them properly for separation during anaphase.
Phase of mitosis when chromosome doublets line up along equatorial plate?
The phase of mitosis when chromosome doublets line up along the equatorial plate is called metaphase. During metaphase, the chromosomes are properly aligned before they are separated into two daughter cells during anaphase.
When is s phase complet?
S phase is complete when each chromosome has been duplicated.
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
What structure will the chromatin become in mitosis?
The chromatin in the cell becomes chromosomes in prophase, the first stage of mitosis. The chromatin coils tightly together to form into separate chromosome strands during this phase.
Which phase is represented when the homologous chromosomes qre lined up along the uqator?
The phase represented when homologous chromosomes are lined up along the equator of the cell is metaphase I of meiosis. During this stage, homologous chromosome pairs align at the metaphase plate, preparing for separation. This alignment is critical for ensuring that each daughter cell receives one chromosome from each pair.
When is Phase complete?
S phase is complete when each chromosome has been duplicated.
What is the Phase of mitosis in which microtubules connect thecentromere of each chromosome to the poles of spindle?
The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.
A structure in the nucleus that is composed of large amounts of DNA?
depending on the phase of the cell cycle it could be a formed chromosome, or the nucleolus which is a large aggregation of DNA and associated proteins.
What is a dark staining body composed of 2 chromatids inside a cell during M-phase?
The dark staining body composed of 2 chromatids inside a cell during M-phase is called a chromosome. Chromosomes are formed when the DNA in a cell is tightly coiled and condensed to facilitate cell division. Each chromosome consists of two sister chromatids that are held together at a structure called the centromere.
What is a middle phase in mitosis when chromosome pairs line up along the middle of a cell?
The middle phase in mitosis when chromosome pairs line up along the middle of a cell is called metaphase. This is a crucial stage where the spindle fibers attach to the centromeres of the chromosomes, ensuring they are properly aligned before separation. Metaphase is followed by anaphase, where the sister chromatids are pulled apart to opposite poles of the cell.
When the cell copies its DNA in order to have full sets of chromosome is what phase?
The process of DNA replication occurs during the S phase (synthesis phase) of the cell cycle. During this phase, each chromosome is duplicated, resulting in two identical sister chromatids for each chromosome. This ensures that when the cell divides, each daughter cell will receive a complete set of chromosomes.
