chapter 11 cell growth and division

Which event occurs during interphase?

• cytoplasm divides
• DNA replicates
• spindle fibers form
• centromeres divide

If cells are removed from tissue, then new cells later fill in that space and stop dividing, it's an example of

• random cell mutations

• physical cell-to-cell contact inhibition

• carcinogenic exposure

• surface area: volume ratio rule

• the petri dish inhibits growth

• most cells grown in petri dishes have a defective p53 gene

An advantage of asexual reproduction over sexual reproduction is
