Question

Predict how each mutation would affect the amount (mass) of DNA in Calix’s cells.

Answer 1

Answer:

no change, increase, increase

Explanation:

(see image below)

Answer 2

Answer:

Point mutation: no change

chromosomal rearrangement: increase

nondisjunction: increase

Explanation: a point mutation only affects a single base pair, so it would not change the amount of dna. if calix had gained an extra allele because of chromosomal rearrangement, his cells would have more DNA. A nondisjunction mutation would cause Calix to have one more chromosome than normal. This would increase the amount of DNA in his cells.
