AP Biology Translation

The anticodon is located on 

• DNA

• mRNA

• tRNA

• rRNA

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though they look and perform completely different?

• The two different cells become mutated

• The proteins expressed in each cell are different

• They actually have different DNA in the two types of cells.

• The genome of the different cells changes

Which of the following would be transcribed from the following DNA sequence? 3' ATC GAA TTA CGA 5'

• 5' UAG CUU AAU GCU 3'

• 5' AUC GAA UUA CGA 3'

• 3' UCG UAA UUC UAG 5'

• 3' TAG CTT AAT GCT 5'

The genetic code is essentially the same for all organisms. From this, one can logically assume all of the following except

• a gene from an organism could theoretically be expressed by any other organism.

• all organisms have a common ancestor.

• DNA was the first genetic material.

• the same codons in different organisms usually translate into the same amino acids.

Introns are significant to biological evolution because

• their presence allows exons to be shuffled.

• they protect the mRNA from degeneration.

A mutation in which of the following parts of a gene is likely to be most damaging to a cell?

• intron

• exon

NGSS.HS-LS3-2

When does translation begin in prokaryotic cells?

• as soon as transcription has begun

• once the pre-mRNA has been converted to mRNA

Why might a point mutation in DNA make a difference in the level of proteinʹs activity?

• It might substitute an amino acid in the active site.

• It might exchange one stop codon for another stop codon.

What is the role of mRNA in the process of translation?

• It carries the genetic code from DNA to the ribosome.

• It forms the structure of the ribosome.

• It brings amino acids to the ribosome.

• It catalyzes the formation of peptide bonds.

Which of the following components is directly involved in the process of translation?

• DNA polymerase

• RNA polymerase

• Ribosome

• Helicase
