The main function of tRNA is to...

• carry a message that, when translated, forms proteins
• form a portion of ribosomes
• string together complementary RNA and DNA strands
• bring amino acids from the cytoplasm to the ribosomes

mRNA contains which bases?

• adenine, guanine, uracil, cytosine

• thymine, guanine, cytosine, uracil

• thymine, uracil, cytosine, guanines

• adenine, uracil, guanine, thymine

A protein may not have the same function if...

• its structure has been altered.

• it's produced by a ribosome.

• its structure is intact.

• it's synthesized during translation.
