a somatic cell undergoes ________ and results in 2 genetically __________ cells.
mitosis; identical
The phase in which the cell is preparing for division
Interphase
stage of interphase where the cell prepares for replication by producing all the enzymes required for DNA replication and duplicates most of its organelles is called
G1
stage of interpgase wgen DNA is replicated. The two strands of the DNA helix separate and become the template for the new complimentary___________
S phase; nucleotides
When S phase is finished the original DNA molecule has become two identical DNA molecules that are attached together at the ____________ and are now known as sister _________
centromere; chromatids
Stage of interphase that is devoted to last minute protein synthesis as cell prepares to divide.
G2
Phase of interphase where some cells go temporarily and other never leave. The cells that enter this phase are considered to be in their normal functioning state. Muscle and nerve cells are an example of these.
G0 phase
In this mitotic phase, chomotin condense to form chromosomes
prophase
During prophase chromatids are held together at a region called the
centromere
centrosomes/centrioles begin to sepaerate and move toward opposite ends of the cell and produce the mitotic spindle
prophase
the ___________ is a molecular motor on each side of the centromere
kinetichore
type of microtubules that expand to opposite poles and lengthen the cell. These microtubules oriented parallel to each other but in opposing directions, and are crucial for pushing the centrosome and spindle apparatus apart
Polor microtubules
type of microtubules that are short and are attached to the cell membrane/cytoskeleton and anchor the centrosomes into position
aster microtubules
What is the correct sequence of the cell cycle beginning with interphase is:
G1, S G2, mitosis
Nuclear envelope reappears and encloses chromosomes, chromosomes resume chromatin form, nucleoli reappear, and mitotic spindle disappears.
telophase
Chromatin coils and condenses to form chromosomes
prophase
