Nucleus
Ribosome
Rough ER
Golgi Apparatus

You are explaining protein synthesis to your grandmother, using her old heirloom cookbook as an analogy. "Imagine this cookbook is the DNA in each of your cells," you say. "You copy down one recipe on a scrap of paper and take it to the kitchen to make gingerbread cookies." Which of the following has the correct analogy?
scrap paper is mRNA, kitchen is the ribosome, cookies are the protein
scrap paper is tRNA, kitchen is mRNA, cookies are the ribosome
scrap paper is the nucleus, kitchen is ribosome, cookies are tRNA
scrap paper is ribosome, kitchen is mRNA, cookies are delicious.
During which processes is the DNA unzipped or split open?
Three bases of mRNA with the information to code for one amino acid are called a ______________.
anti-codon
codon
gene
mutation
What is the role of mRNA in protein synthesis?
It carries the information on how to make a protein from the nucleus to the ribosome.
DNA turns into mRNA.
mRNA turns into protein.
mRNA carries amino acids to the ribosome.
What is the job of tRNA in protein synthesis?
Carry the message from the nucleus to the ribosome
Carry amino acids to the ribosome during translation
Carry DNA to the ribosome
help make mRNA codons in transcription
Name two different types of proteins and describe what each type does. Provide an example of one of these.
If the codon chart tells us which amino acid gets added based on the mRNA codons, what is the point of the tRNA and the anticodons?
Write two ways that DNA and RNA are similar and two ways that they are different.
