Match the following to their role in protein synthesis.

Draggable item		Corresponding Item
tRNA		Copies the genetic code from the DNA molecule and carries it to the ribosome.
mRNA		Stores the genetic code in the nucleus.
DNA		Carries an amino acid to the ribosome.

A mutation always results in the incorrect protein being produced.

True

False

Which nitrogenous bases are needed to complete the DNA strand pictured below? Give your answer in order, from top to bottom.

adenine
thymine
guanine
cytosine

How would the mRNA built from the same DNA strand in #7 be different?

Uracil (U) pairs with adenine (A)

Uracil (U) pairs with thymine (T)

Adenine (A) pairs with guanine (G)

Match the process to its definition.

Draggable item		Corresponding Item
Translation		The process of creating an mRNA strand from one side of DNA
DNA Replication		The process of using mRNA to build chains of amino acids
Transcription		The process of duplicating a strand of DNA

What is the function of tRNA in protein synthesis?

To combine with other proteins to form the ribosome where protein synthesis takes place

To transfer the amino acids from the cytoplasm to the ribosome where protein synthesis takes place

To match up codons with rRNA to signal the start of protein synthesis
