KC: Protein Synthesis by Amoeba Sisters

What are three ways that DNA & RNA differ?

• DNA has thymine, RNA has uracil

• Both are a nucleic acid

• The sugar in DNA is deoxyribose, the sugar in RNA is ribose

• DNA is a double helix, RNA is a single strand

A sketch of an ________________ helps you remember mRNA.

• envelope

• iphone

• box

• binder

• ribosome, t, amino acids

• ribosome, r, amino acids

• ribosome, r, nucleotides

During translation. the ribosome (rRNA) is finally receiving the message that DNA sent to mRNA and is

• building a necklace called a protein from the beads called amino acids which are brought by rRNA

• building a necklace called a protein from the beads called amino acids which are brought by tRNA

• building a necklace called a protein from the beads called amino acids which are brought by mRNA

At the end of protein synthesis, DNA's genes are finally

• expressed!

• not the right answer
