Homework Answers
I believe the correct answer to be:
Option C) There is uncontrolled cell division.
As that checkpoint no longer works and it will allow the cell division irrespective of its conditions..
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

Which of the following is NOT a checkpoint that controls the progression of the cell cycle? 0 Cyclins and cyclin-dependent kinases are proteins that are responsible for advancing a cell through the phases of the cell cycle. The G2 checkpoint checks for DNA damage and determines if all of the DNA is replicated. The metaphase checkpoint determines if all chromosomes are attached to the spindle apparatus. Cytokinesis involves the formation of cleavage furrow to separate the cells. The restriction point...

Checkpoints are pauses between phases of the cell cycle during which a cell determines whether or not it is ready to proceed to the next phase. For example, because a cell with damaged DNA can lead to cancer if it is allowed to divide, it usually arrests the cell cycle until the damage can be repaired. At which phase(s) of the cell cycle would a cell normally check for the integrity of its DNA? See Section 2.3 (Page 17) View...

QUESTION 7 If you inject a G1 cell that contains 36 chromosomes with a G2/M cyclin, what would happen? (hint - look at slide with cell fusion experiments) The G1 cell would complete mitosis with daughter cells that have 18 chromosomes each The G1 cell would enter mitosis but arrest at the spindle checkpoint because the chromosomes were not properly replicated The G1 cell would complete mitosis with daughter cells that have 36 chromosomes each The G1 cell would go...

Write the letter of the correct answer on the first page. Control of entry into the cell cycle is essential. Unicellular eukaryotes that enter into it too soonyw have the necessary energy to complete it, leading to their demise, whereas in multicellular eukaryotes usually leads to cycle are controlled by proteins, problems with the genes that code for these proteins are a commorn source of error. These genes fall into two broad groups: 33 uncontrolled cellular division 32 Since the...
