Variation

What is a difference between mitosis and meiosis?

• Meiosis is a multi-step process

• Mitosis only occurs in eukaryotic cells

• Meiosis is for growth and repair

• Mitosis makes identical cells

An inversion would cause...

• recessive alleles to become dominant

• the information to be read differently

• the coding sequence to disappear

• multiple frameshift errors in the region

Which mutation would cause a frameshift change to occur?

• Delete 2 nucleotides

• Delete 3 nucleotides

• Delete 6 nucleotides

• Delete 9 nucleotides

What occurs during meiosis but not mitosis?

• Crossing over

• Gene mutation

• Nuclear division

• Replication of DNA

What would nondisjunction most likely cause?

• An increase in nuclei

• An extra chromosome

• Only two types of bases

• Increased benefits
