The offspring of the plant will also produce the chemical. What is the most likely, possible, disadvantage of growing this type of potato?
Killer Potato: Potatohead
a
Resistance developed to the chemical by harmful insects.
b
Increased bioluminescence/attraction to fireflies.
c
Decreased nutrient composition in crops.
d
Significantly decreased harvest production of the potatoes.

DNA carries the cell’s genetic information; however, it cannot leave the .
Because of this, it copies part of its nucleotide sequence into a complementary copy of
during the process called .
During this process, the enzyme,
separates the DNA strands.
One strand of DNA acts as the
from which nucleotides are assembled into a strand of RNA.
Each three letter sequence on the mRNA is called a .
The start codon is and the three stop codons are .
Once the mRNA leaves the nucleus, it goes to the to prepare for protein
synthesis, which is called .
During this process, a molecule brings the to the ribosome.
The amino acids are hooked together by bonds.
The tRNA is able to match up to the mRNA by the in its anticodons.
When the codon is reached, the chain is released into the .
