Which of the following is NOT true about mitosis?
The chromosome number in the resulting cells is the same as parent cell's chromosome number
The number of chromosomes of the daughter cells is one-half of the parent cell's chromosomes.
Mitosis is also a mode of asexual reproduction
DNA replication is completed prior to mitosis during the S- phase.
What is the longest stage of the cell cycle?
Interphase
Mitosis
Cytokineses
The cell cycle is described as ?
a period during which the cell undergoes growth
an ordered series of events that leads to cell growth and division into two daughter cells
the DNA replication.
division preparation and organelles are duplicated
In the cell cycle diagram, when does DNA make exact copy of itself?
Mitosis ( M-phase)
Synthesis or S-phase
G2
What does phase C represent in the diagram?
Mitosis
G2
G1
What is the function of Phase B?
the chromosomes enter a relaxed state that allows the enzyme DNA polymerase to access the DNA double helix inside each chromosome.
extra protein is often synthesized, and the organelles multiply until there are enough for two cells.
the cell synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division.
The spliting or division of the cytoplasm with two complete daughter cells is called _____________.
Metaphase
teleophase
anaphase
cytokinesis
During this phase, the chromosomes are duplicated and organelles are duplicated
Interphase
metaphase
anaphase
cytokinesis
This is the genetic material composed of DNA, which can be visibly seen in the nucleus of a cell during the process of cell division .
Chromosomes
Organelles
Endoplasmic Reticulum
Microtubule structures, called _____________________ help the centrioles separate the chromosomes during cell division.
Centromeres
Spindle Fibers
Sister Chromatids
Cell Plates
The relaxed form of DNA which appears like thread-like form in the nucleus of a cell during the interphase is called ______.
Chromatin
chromosome
sister chromatids
The chromosomes are pulled apart at the centromere and each replicated half migrates toward the poles
along the spindle fibers.
Los cromosomas se separan en el centrómero y cada mitad replicada migra hacia los polos a lo largo de las fibras del huso.
Prophase
Anaphase
Telophase
Metaphase
