What cellular process would be directly affected by a catalyst that blocked a certain step in the separation of chromosomes?
mitosis
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
true
What shape do the chromosomes forms in mitosis?
During anaphase, there is separation of the duplicated centromeres from the paired sister chromatids. As the chromosomes move towards the poles of the cell, they take the shape of letter V.
What cellular process would be directly affected by a biological catalyst that blocks a certain step in the separation of chromosomes?
mitosis
Marine sponges contain a biological catalyst that blocks a certain step in the separation of chromosomes Which cellular process would be directly affected by this catalyst?
Mitosis.
What organelles are crucial to separation of chromosomes?
The centrosomes, fit with two centrioles, produce spindle fibers. Some, specifically called kinetochore fibers, will attach to the centromeres of the chromosomes.
What are the two process that closely occur in mitosis?
Replication of DNA and separation of sister chromosomes.
What is the random separation of maternal and paternal chromosomes during anaphase 1?
independent assortment
What occurs in meiosos but not in mitosis?
lining up of tetrads, crossing over, and separation of homologous chromosomes.
What is the separation of homologous pairs of double chromosomes during meiosis?
the stage is called the "first division"
What cellular process would be directly affected by a catalyst that blocked a certain step in the separation of chromosomes?
mitosis
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
true
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
How would you describe the process of meiosis?
Meiosis is a process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.
What are the fibers that form around centrioles of an animal cells during the reproduction of the nucles?
Spindle fibers form from centrioles of animal cells during chromosomal separation in mitosis. These fibers elongate to reach the kinetochores of chromosomes, and then retract via depolymerization from each end of the dividing cell leading into cytokinesis.
How does the centriole affect the animal cell?
It aids in the separation of lined up chromosomes, the centriole produces fibers that attach and pull ideniticle chromosomes to opposite poles of the cell. Anaphase 1
What cellular process would be directly affected by a biological catalyst that blocks a certain step in the separation of chromosomes?
mitosis
