Question 1, , 1 / 1 point If there are 8 centromeres in metaphase, how many centromeres will be present in anaphase? Question options: 4 8 16 32 View question 1 feedback Question 2, , 1 / 1 point If a researcher looks at a cell and notices a straight line of sister chromatids, which phase are they viewing? Question options: interphase prophase prometaphase metaphase anaphase telophase View question 2 feedback Question 3, , 1 / 1 point When the p53 gene is damaged, which event may happen? Question options: Cells can divide uncontrollobly Cells will fix the DNA pass the G1 checkpoint Cells will pass the G2 checkpoint Cells will always undergo apoptosis View question 3 feedback Question 4, , 1 / 1 point Which molecule initiates the halt of the cycle when damaged DNA is detected in G1? Question options: Rb p53 Cdk/cyclin complex p21 E2F View question 4 feedback Question 5, , 1 / 1 point In nature, there is an exception to every rule. Of the species below, which one has a very unusual genome that violates the "rule"? Question options: Borrelia burgdorferi, the bacterium responsible for Lyme disease, has a linear genome and up to 21 plasmids. E. coli, a common bacterium in the human intestine, has DNA nucleotides A, T, C, and G, with only one OH group on the sugar moiety. Humans have a genome formed from 23 pairs of linear chromosomes, each of which is so long that it must be wrapped up and condensed into a special structure to fit in the nucleus. Arabidopsis pollen is haploid, carrying only one copy each of five linear chromosomes. View question 5 feedback Question 6, , 0 / 1 point In which type of human cell(s) would 46 chromosomes be located? Select all that apply. Question options: diploid egg somatic gamete sperm haploid View question 6 feedback Question 7, , 1 / 1 point Place the order of events in chromosome packaging from beginning to end. Question options: DNA double helix, nucleosome, sister chromatids, chromatin sister chromatids, DNA double helix, chromatin, nucleosome Chromatin, nucleosomes, DNA double helix, sister chromatids DNA double helix, chromatin, nucleosomes, sister chromatids View question 7 feedback Question 8, , 1 / 1 point A large cell will be initiated to divide because Question options: a decrease in surface-to-volume ratio an increase in surface-to-volume ratio crowding from smaller cells large cells do not experience quiescent stage large cells use more nutrients than small cells View question 8 feedback Question 9, , 1 / 1 point A cell's entire amount of hereditary information is the Question options: nucleoid nucleus genome DNA View question 9 feedback Question 10, , 1 / 1 point Damaged DNA can potentially be repaired during which checkpoint. Select all that apply. Question options: G1 S G2 G0 M
