DNA Replication & 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

How many codons equals 1 amino acid?

• 1

• 2

• 3

• 4

How many nucleotides equal 1 amino acid?

• 1

• 2

• 3

• 4

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

• Met-His-Stop

• Thr-Glu-Stop

• Thr-Pro-Stop
