Protein Synthesis and DNA

In what process is mRNA synthesized?

• Transcription

• Translation

• DNA Replication

• Mitosis

Where does TRANSCRIPTION occur?

• Nucleus

• Ribosome

• Cytoplasm

• Mitochondria

Why must transcription occur where DNA can be found?

• because DNA can't leave

• because ribosomes are in the nucleus

• because DNA polymerase is found there

• because helicase unzips the DNA

Which of the following is a codon?

• 
• ATG

• AUG

• AUT

How many codons equals 1 amino acid?

• 1

• 2

• 3

• 4

How many nucleotides equal 1 amino acid?

• 1

• 2

• 3

• 4

On which molecule can an anticodon be found?

• mRNA

• DNA

• tRNA

• rRNA

Where is the anticodon located?

• at the top of the molecule it's found on

• at the bottom of the molecule it's found on

• on the right of the molecule it's found on

• on the left of the molecule it's found on

What is the purpose for anti-codons?

• to ensure the correct amino acid is dropped off

• to match the strand of DNA

• to decode a sequence of 4 nucleotides into an amino acid

• to make me hate biology

A polypeptide is a sequence of ____________________ held together by a ______________ bond.

• amino acids; peptide

• fatty acids; ionic

• proteins; hydrogen

• fatty acids; covalent
