Multiple Choice

What is the difference between mRNA and tRNA?

• mRNA carries genetic information; tRNA transfers amino acids for protein synthesis.
• mRNA is a type of protein; tRNA is a type of DNA.
• mRNA transports nutrients; tRNA synthesizes lipids.
• mRNA is involved in cell division; tRNA is involved in DNA replication.

Vocab Match

• The process where RNA instructions are used to assemble proteins in the ribosome.

• Messenger RNA; it carries the code from DNA that tells the ribosome how to make a specific protein.

• Transfer RNA; it brings amino acids to the ribosome and matches them to the mRNA code using its anticodon.

• A sequence of three bases on tRNA that pairs with the matching codon on mRNA during translation.

• A strong bond that links amino acids together to form a protein.
