Protein Synthesis AP Bio

What is the role of mRNA

• Carry an amino acid to the ribosome

• Copy the instructions from DNA and carry it out of the nucleus

• Make up the ribosomes

Where does Transcription occur

• Nucleus

• Ribosome

• ER

• Mitochondria

What is the mRNA for the following DNA strand?

TAC GTA

• GCT AGC

• ATG CAT

• AUG CAU

Where does Translation occur?

• Nucleus

• Ribosome

• ER

• Chloroplast

What is an anticodon?

• rRNA

• an amino acid

• Three nucleotide sequence found on mRNA

• Three nucleotide sequence found on tRNA

How many possible codons are there??

• 64

• 3

• 20

• Infinite

what does a promoter do?

• it allows a gene to be transcribed

• it creates a DNA segment

• it is another word for ribosomes

• it is another word for RNA

In eukaryotic cells, transcription cannot begin until 

• the two DNA strands have completely separated and exposed the promoter.

• several transcription factors have bound to the promoter.

• the 5' caps are removed from the mRNA.

• the DNA introns are removed from the template.

How many nucleotides code for each amino acid?

• 1

• 2

• 3

• 64

What is the relationship between a protein, a cell, and DNA?

• DNA -> Protein -> RNA

• Protein -> RNA -> DNA

• RNA -> DNA -> Protein

• DNA -> RNA -> Protein
