Three ways mutations can occur in genes are: 1. Insertion: Extra DNA nucleoties are added to the DNA strand. 2. Deletion: DNA nucleotides are deleted, therefore, changing the â¦ DNA sequence. 3. Translocation: parts of chromosomes are exchanged.or example, this can happen during crossover during the formation of gametes. Substitution mutations happen when one nucleotide (the smallest unit of DNA) is replaced by another. These are caused by a number of chemicals that look like something in between both of those nucleotides.

Cure the sweet potatoes for 1 to 2 weeks. Keep the roots in a room or other location that reaches between 75 and 80 degrees Fahrenheit (24 and 27 degrees Celsius) with relative humidity of 90 to 95 percent.1  The sweet potatoes need to cure for at least 7 days, but they can be kept there for as many as 14 days. The sweet potatoes need to cure for at least 7 days, but they can be kept there for as many as 14 days. 2  The curing process creates a second skin that forms over scratches and bruises, allowing the sweet potatoes to last longer in storage.
