Term
What is a gene?
Definition
a group of DNA that determines a trait
Term
What is a mutation?
Definition
A mistake in the DNA during replication
Term
What is a ribosomes' job during protein synthesis?
Definition
Makes proteins that will be used for DNA production.
Term
How is eating the proper food related to protein synthesis?
Definition
Without the proper foods your body can't produce the correct DNA sequence, which will cause your body to work improperly. EXamples:  make wrong cells, can't heal properly.
Term
