Experiments show that normal cells will reproduce until they come into contact with each other. This is known as:
What is contact inhibition
300
Which of the following is NOT a phase of mitosis? a. Prophase b. Megaphase c. Anaphase d. Telophase
What is b
300
Following replication, each duplicated chromosome consists of two identical _________.
What are sister chromatids
300
Genetic information is passed from one generation to the next on ___________________, packages of DNA.
What is chromosomes

What is d
400
During ______________________, the chromosomes gather at opposite ends of the cell the spindle begins to break apart as a nucleolus becomes visible in each daughter nucleus.
What is telophase
400
