Protein Synthesis

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

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

How do you know when to begin translating a strand of mRNA?

• look for AUG

• start at the beginning

• look for ATG

• when Ms. H tells me to

How do you know when to STOP translating a strand of mRNA?

• look for STOP on the decoder

• stop at the end of the strand

• you don't

• when Ms. H tells me to
