Protein Synthesis-Transcription and Translation

By Jessica Brink

Multiple Choice

Where does Transcription occur?

• The nucleus

• The mitochondria

• The cytoplasm

• My basement

Multiple Choice

True or False?

During transcription RNA Polymerase attaches to a specific sequence of DNA to unzip the strand so one molecule of mRNA can be made.

• True

• False

Multiple Choice

There are segments of genetic material that do not code for anything. Once the mRNA is made, enzymes in the nucleus remove the non-coding segments. What are these non-coding segments called?

• Introns

• Exons

Multiple Choice

True or false?

The removal of the non-coding segments or introns is called RNA splicing.

• True

• False

Multiple Choice

Which of the following is the complementary strand of mRNA made from the following strand of DNA?

ACG GTC TAC

• TGC CAG ATC

• UGC CAG AUG

• ACG GTC TAC

Multiple Choice

How many bases make a codon?

• 1

• 2

• 3

• 4

Multiple Choice

How many possible Amino Acids are there?

• 10

• 3

• 20

• 17

Multiple Choice

True of False?

Transfer RNA (tRNA) brings specific amino acids to the ribosome to be assembled as proteins.

• True

• False

Multiple Choice

True or False?

We use codon charts to translate the sequence of codons from mRNA into corresponding amino acids.

• False

• True
