Unit 3 Test Review

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 the nucleus

• because ribosomes are in the nucleus

• because DNA polymerase is found there

• because helicase unzips the DNA

Which of the following is a codon (think RNA)?

• 
• ATG

• AUG

• AUT

On which molecule can an anticodon be found?

• mRNA

• DNA

• tRNA

• rRNA

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

Which two thing are found on a molecule of tRNA?

• amino acids; anticodons

• amino acids; codons

• ribose sugar; proteins

• deoxyribose sugar; codons

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
