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
Which two thing are found on a molecule of tRNA?
amino acids; anticodons
amino acids; codons
ribose sugar; proteins

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
