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

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

The correct answers are :
The point mutation – no change
The chromosomal rearrangement – increase
The non-disjunction – increase

What is mutation?
The mutation that is changes in the DNA sequence and can result from the copying mistakes that are made during cell division, exposure to ionization and exposure to chemicals and many more.
The point mutation affects the single base pair, hence it could not change the amount of DNA.

if Calix is gained by the extra allele due to chromosomal rearrangements of cells.
The nondisjunction mutation creates Calix with one more chromosome thus increasing the DNA in cells.
