True

200

Proteins are made up of long chains of __________.

Amino acids

300

If a frameshift mutation from exposure to radiation caused a segment of RNA to change from AUC to UAG, what would happen to the protein during translation?

It would stop

400

What amino acid would pair up with the beginning DNA bases TAC?

Methionine

500

If exposure to radiation caused a segment of DNA to change from TTC to TTT, what would happen to the protein during translation?

Nothing would happen

Transcription & Translation

100

The process where mRNA copies the genetic code from DNA is called __________.

Transcription

Where does translation take place?

In the cytoplasm at a ribosome

400

What is the purpose of transcription and translation?

To make a protein

Potpourri

100

Name one thing in our bodies that is made of protein.

Skin, muscles, hair, enzymes, hemoglobin, etc.

200

True or False:

An error in transcription is considered a mutation.

False. An error in the DNA sequence is considered a mutation. An error in transcription does not affect the sequence of DNA.
