• Studying gene expression

What is the main difference between genes and short tandem repeats (STRs)?

• Genes are unique to each individual, while STRs are the same for everyone

• Genes determine physical traits, while STRs determine genetic diseases

• Genes are found in the middle of DNA, while STRs are found at the ends

• Genes have multiple copies, while STRs have only one copy
