AP Biology DNA, RNA, and Protein Synthesis

Where does transcription occur in eukaryotic cells?

• Nucleus
• Ribosome
• Cytoplasm
• Rough E.R.

What is the complementary tRNA anticodon to the following mRNA codon: AUG

• UAC
• TAC
• ATG
• AAC

A certain gene codes for a polypeptide that is 120 amino acids long. Approximately how many nucleotides long is the mRNA that codes for this polypeptide likely to be?

• 360
• 480
• 40
• 30

Transcribe the following DNA sequence:
TAT GGC ACT 

• TAT GGC ACT
• ATA CCG TGA
• AUA GGC UGA
• UAU GGC ACU

Translate the following RNA sequence:
AUG AAU UGU UGA

• Met-Phe-Cys-Stop
• Met-Asn-Cys-Stop
• Met-Asn-Cys-Trp
• Tyr-Leu-Thr-Thr

What is the complementary RNA sequence for the following:
ATC AAT CGT TAG

• TAG TTA GCA ATC
• UAG UUA GCA AUC
• AUC AAU CGU UAG
• GCT GGC TAC CGA

What is the amino acid sequence for the following:
GGG GCA CAT CAC

• Gly-Ala-His-His
• Tyr-Arg-Val-Val
• Pro-His-Val-Val
• Pro-Arg-Val-Val

 A frameshift mutation could result from 

• a base insertion only.
• a base deletion only. 
• a base substitution only. 
• either an insertion or a deletion of a base.

The anticodon of a particular tRNA molecule is 

• complementary to the corresponding mRNA codon.
• complementary to the corresponding triplet in rRNA.
• the part of tRNA that bonds with a specific amino acid.
• catalytic, making the tRNA a ribozyme.

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.
