What is the phase of mitosis where the chromosomes lines at the center?
The phase of mitosis where the chromosomes line up at the center of the cell is called metaphase. At this stage, the spindle fibers attach to the centromeres of the chromosomes, aligning them along the metaphase plate in preparation for their separation.
What pairs are correctly matched g1 phase-dna replication g2 phase-preparation for meiosis s phase- dna replication m phase-cell growth go phase-cell growth?
The correct pair is: G1 phase: Cell growth G2 phase: Preparation for mitosis S phase: DNA replication M phase: Cell division G0 phase: Quiescent state
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.
What does not belong G1 phaseG2 phaseS phase telophase and why?
Telophase does not belong because it is a stage of mitosis, while G1 phase, G2 phase, and S phase are stages of interphase. Telophase is specifically involved in the final separation of chromosomes into two daughter nuclei, whereas the other phases are involved in cell growth, DNA replication, and preparation for cell division.
What is the mechanism of separation in thin layer chromatography?
In thin layer chromatography, separation is based on differences in the affinity of compounds for the stationary phase (usually a silica gel plate) and the mobile phase (solvent). As the mobile phase moves up the plate, compounds with higher affinity for the mobile phase move faster, leading to separation based on their different polarities or interactions with the stationary phase.
During which phase does the actual separation of the nuclear material occur?
anaphase

How does the crescent phase that precede the new moon differ from the crescent phase that follows the new moon?
One is Crescent (waxing), the other is Crescent (waning).
Why do some scientists not think interphase is a phase of mitosis?
Some scientists do not consider interphase a phase of mitosis because interphase is the stage of the cell cycle where the cell prepares for mitosis, rather than actively dividing. During interphase, the cell undergoes growth, DNA replication, and preparation for division, but it does not involve the processes of chromosome alignment, separation, or cytokinesis that characterize mitosis. Therefore, interphase is seen as a preparatory phase rather than a part of the actual mitotic process.
What is the difference between reverse phase and normal phase chromatography?
Normal Phase: It has a polar stationary phase and a non-polar mobile phase.Reverse Phase: It has a non-polar stationary phase and a moderately polar mobile phase
Which phase of a cell's lifecycle involves growth and preparation for cell division?
The interphase stage of a cell's lifecycle involves growth and preparation of the cell for division. Interphase includes the G1 phase, the S phase, and the G2 phase. The G1 and G2 phase includes production of proteins and cytoplasmic organelles. The S phase is the phase where chromosomes are duplicated.
What is a method of separation that employs a system with two phases of matter a mobile phase and a stationary phase?
Chromatography is a method of separation that employs a system with two phases of matter – a mobile phase and a stationary phase. The mobile phase carries the mixture to be separated through the stationary phase, where the components separate based on their interactions with the stationary phase.

What phase kinetochores are motionless in relation to poles of cell?
During metaphase, kinetochores are motionless in relation to the poles of the cell. This helps ensure proper alignment of chromosomes along the metaphase plate in preparation for their separation during anaphase.
