| 1558207799 | through a microscope you can see a cell plate beginning to develop across the middle of a cell and nuclei forming on either side of the cell plate. The cell is most likely | a plant cell in the process of cytokinesis | 0 | |
| 1558207800 | Vinblastine is a standard chemotherapeutic drug used to treat cancer. Because it interferes with the assembly of micrtubles, its effectiveness must be related to | description of mitotic spindle formation | 1 | |
| 1558207801 | one difference between cancer cells and normal cells is that | cancer cells continue to divide even when the are affected by densty-dependent inhibition | 2 | |
| 1558207802 | the decline of MPF activity at the end of mitosis is due to | the degradation if cyclin | 3 | |
| 1558207803 | In the cells of some organisms, mitosis occurs without cytokinesis. This will result in | cells with more than one nucleus | 4 | |
| 1558207804 | a paticular cell has half as much DNA as some other cells in a mitotically active tissue. This cell is most liekly in | G1 | 5 | |
| 1558207805 | The drug cytohalasin B blocks the function of actin. What aspects of an animal cell cycle would be most disrupted by cytochalasin B? | cleavage furrow and cytokinesis | 6 | |
| 1558207806 | A human cell containing 22 automsomes and Y chromosome is a | sperm | 7 | |
| 1558207807 | which life cycle stage is found in plants but not in animals | unicellular diploid | 8 | |
| 1558207808 | Homologous chromosomes move toward opposite poles of a dividing cell during | meiosis I | 9 | |
| 1558207809 | meiosis II is similar to mitosis in that | sister chromatids separate during anaphase | 10 | |
| 1558207810 | If the DNA content of a diplod cell in the G1 phase of the cell cycle is X, then the DNA content of the same cell at metaphase of meiosis would be | 2X | 11 | |
| 1558207811 | What is the badic differnce in how the leading and lagging strands of DNA molecules are synthesized? | DNA polymerase can join new nucleotides only to the 3' end of the growing strand | 12 | |
| 1558207812 | In analyzing the number of the different bases in DNA sample, which result would be consistent with the base pairing rules? | A+G=C+T | 13 | |
| 1558207813 | the elongations of the leading strand during DNA synthesis | depends on the action of DNA polymerase | 14 | |
| 1558207814 | In a nucleosome, the DNA is wrapped around | histones | 15 | |
| 1558207815 | In eukaryotic cells, transcription cannot begin until | several transcription factors have bound to the promoters | 16 | |
| 1558207816 | the anticodon of a particular tRNA molecule is | complementary to the corresponding mRNA codon | 17 | |
| 1558207817 | what mutation would likely to have a harmful effect on and organism | the single nucleuotide insertion downstream of, and close to, the start of the coding sequence | 18 |
