- 2.
This type of RNA codes for a protein
-
TRNA
-
MRNA
-
RRNA
-
No RNA codes for protein
Correct Answer
A. MRNAExplanation
mRNA stands for "Messenger RNA" (coding)Rate this question:
-
- 3.
An mRNA that has 1200 nucleotides can code for a protein of this many amino acids
-
1200
-
400
-
3600
-
None
Correct Answer
A. 400Explanation
Each amino acid requires 3 nucleotdies (one codon)Rate this question:
-
- 4.
The correct order of events is
-
Transcription, translation,splicing
-
Splicing, transcription, translation
-
Transcription, splicing, translation
-
Translation, Splicing, Transcription
Correct Answer
A. Transcription, splicing, translationExplanation
The RNA is made, the introns are remove, and the mRNA is then translated to proteinRate this question:
-
- 5.
The tRNA that is base pairing with the codon is in the
-
A site
-
P site
-
E site
-
None of the above
Correct Answer
A. P siteExplanation
The P site is the middle of the 3 ribosome sites. tRNAs move there after the peptide bond is formedRate this question:
-
- 6.
A section of DNA is 5' AAA TTT CAT 3' If this is transcribed and translated, the resulting amino acid sequence is
-
LYS PHE HIS
-
PHE LYS VAL
-
MET LYS PHE
-
MET PHE LYS
Correct Answer
A. MET LYS PHEExplanation
The mRNA is 5'AUG AAA UUU3' which gives MET LYS PHERate this question:
-
- 7.
If the anticodon is 5'AGC3' then the amino acid attached to the codon is (Use your codon table)
-
Cys
-
Gly
-
Ala
-
A stop codon
Correct Answer
A. AlaExplanation
The codon (from the previous question is GCU, so the amino acid is AlaRate this question:
-
- 8.
If the anticodon is 5'AGC3' then the codon is
-
5'UCG3'
-
5'TGC3'
-
5'AGC3'
-
5'GCU3'
Correct Answer
A. 5'GCU3'Explanation
The anticodon and codon pair and they run in opposite directions (anti parallel)Rate this question:
-
- 9.
Deleting a nucleotide will
-
Have no affect on the amino acid sequence since a codon is 3 letters
-
Will change all amino acids in the protein
-
Will change amino acids that are coded 3' to the deletion
-
Will change amino acids that are coded 5' to the deletion
Correct Answer
A. Will change amino acids that are coded 3' to the deletionExplanation
The Ribosome will read the sequence as in the original sequence until it gets to the deleted sequence, then it will be "Out of frame" (reading different codons then in the original sequence)Rate this question:
-
- 10.
The DNA in the section above changes to 5' TTA TTT CAT 3' If this is transcribed and translated, the resulting amino acid sequence will be (compared to the sequence in the qeustion above) (Use your codon table) The amino acid sequence in the previous question was MET LYS pHE
-
Have one less amino acid
-
Have one more amino acid
-
Have the same number of amino acids,but one will be different
-
The amino acids will not change at all
Correct Answer
A. Have one less amino acidExplanation
The changes results in a change of UUU to UAA which is a stop codonRate this question:
-
- 11.
The muscular dystrophy gene has 97 exons, therefore it has this many introns:
-
97
-
96
-
98
-
No gene can have that many introns
Correct Answer
A. 96Explanation
There is always once less exon than intronRate this question:
