QuestionAnswer
The attachment of which molecules is critical for the proper separation of sister chromatids? microtubules
Following S phase, a human cell would have how many pairs of sister chromatids and individual DNA molecules? 46 pairs of sister chromatids and 184 individual DNA molecules
Microtubules become shorter, pulling chromatids to the ends of the spindle, during anaphase
Which one of the following represents interphase? G1 + G2 = S
You are studying cell cycle progression in an early frog embryo. If you were to inject a protein synthesis inhibitor into a cell at the end of S phase, the cell would arrest in G2.
You are assembling a model of a chromosome, but begin having some trouble when you get to the solenoids. If you are unable to resolve this problem, which of the following steps of chromosome structure would you be unable to achieve? chromatin loop
The number of chromosomes characteristic of eukaryotes, in general, vary considerably from 2 to over 1000 in different species.
The division of a bacterial cell occurs as the plasma membrane pinches inward constricting the cell.
The proteins that participate in the functioning of the checkpoints for cell cycle control are cyclins and cyclin-dependant kinases.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the spindle apparatus.
Cytokinesis occurs right after telophase.
PLANT cells typically achieve cytokinesis by forming a cell plate across the middle of the cell.
Which of the following cell functions are maintained by cell division? growth and reproduction
The actual process of cell division in prokaryotic cells is called binary fission.
The cell organelles replicate prior to genomic separation in ______ phase. G2
ANIMAL cells typically achieve cytokinesis by forming a cleavage furrow that pinches the cell into two.
The chromosomes line up at the equator of the spindle during metaphase.
Diploid organisms use meiosis for the development of gametes. Meiosis consists of how many rounds of nuclear division? two
Evidence of crossing over can often be seen under the light microscope as a structure known as a ________. chiasma
The point of connection between the two sister chromatids before anaphase of mitosis separates them is called the centromere.
You are studying meiosis in an organism that has 28 chromosomes as its diploid number. How many chromosomes will the cell have after meiosis II, but before cytokinesis? 28
In one of the first steps in meiosis, the homologous pairs of chromosomes pair up alone their length.
Crossing over chromosomes takes place in prophase I.
The reduction division that separates two haploid complements from each other is called meiosis.
Four chromatids are held together by a zipper-like structure. synaptonemal
You are comparing the events of meiosis I in cells from several different organisms. You come across one species in which you do not observe any chiasmata. Based on this information you are observing achiasmata segregation in Drosophilia males.
