1. how does a mutation in the p53 protein cause cancer cells to divide uncontrollably?

(select all that apply.)

a cytokinesis occurs after each phase of the cycle instead of just after mitosis.

b cells with damaged dna are not signaled to self-destruct.

c the cell cycle cannot be halted if dna damage is detected.

d two of the three checkpoints no longer work.

I'll try my best!

This condition is rare, and is known as Li-Fraumeni syndrome. However, mutations inp53 are found in most tumor types, and so contribute to the complex network of molecular events leading to tumor formation. The p53 gene has been mapped to chromosome 17. Thus cells divide uncontrollably, and form tumors.

So, it would be most likely C or eithier A. My most likely answer is C in my opinion. But you can pick the one that you think works. You can read the paragraph on top of this to figure it out if you want.

I hope this helps! and I hope I solved this under 20 minutes or around! ^^

chordata is the answer

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
