A codon is:
three amino acids on a polypetide that are snipped off by the helicase enzyme
sets of nucleotides on the tRNA, opposite the anti-codon sequence
an mRNA component that specifies a specific amino acid
that which attaches to the mRNA triplet sequence
a don that goes with another don
the protein that begins transcription by breaking H bonds
The reading frame of a protein is determined by
the first nucleotides in the mature mRNA sequence.
the location of the promoter sequence.
the location of the start codon.
the location of the 5' Cap.

- Which of the following is least likely following translation termination? The polypeptide is released. The mRNA is reused. The ribosome is reused. The polypeptide is immediately active.arrow_forwardTRNA is a type of RNA molecule. required for accurate translation. all of the choices are correct. brings the appropriate amino acid to the A site.arrow_forwardWhich of the following is responsible for the ability of one gene to code for more than one type of polypeptide (protein)? O Alternative splicing. O Translation. O Exon shuffling. O Transcription.arrow_forward
- As bacterial DNA replicates, a point mutation occurs in which an A nucleotide is changed to a C nucleotide. Although the mutation changes the codon sequence, it does not change the resulting amino acid in the protein. This would best be described as a missense mutation. splicing site mutation. frameshift mutation. nonsense mutation. silent mutation.arrow_forwardIntrons are known to contain termination codons (UAA, UGA, or UAG), yet these codons do not interrupt the coding of a particular protein. Why? More than one termination codon is needed to stop translation. Exons are spliced out of mRNA before translation. They are not in the correct reading frame. Introns are removed from mRNA before translation.arrow_forwardWhich of the following is NOT an event associated with translation termination? A stop codon enters the A site on the ribosome. A Release Factor enters the A site A terminal amino acid is added to the polypeptide to signal the end of translation. Release Factor mediates the hydrolysis of the polypeptide from the tRNA at the P site. The polypeptide and tRNA are released and the ribosomal subunits are separated.arrow_forward
- Which would have the most serious effect on polypeptide product?arrow_forwardThe sequence: ATTGCCGACGACTTG is complementary to a sequence that is used as a template in transcription in order to make an mRNA that can be translated by the ribosome to make a useful protein. This MRNA has the sequence AUUGCCGACGACUUG, and it is: O (+) Sense O There is too little information. O (-) sensearrow_forwardWhat term is used to describe the sequence on the tRNA that is complementary to mRNA? Complementary sequence Codon Anti-codon Anti-anticodonarrow_forward
- In the role of the P-site and A-site what is: The Processes in the Central Dogma. Identify where the polymerization reaction occurs. Identify in which direction the ribosome moves along the mRNA. How does translation terminate?arrow_forwardTranscription and translation are separate processes in gene expression; however, they have similarties. The following terms all relate to translation. Which of these has a role that is most similar to that of the transcription start sit during transcription ? A- Start Codon B- Stop Codon C- tRNA D- Amino Acidarrow_forwardWhich of the following types of mutation that changes the mRNA sequence after the codon that initiates translation is likely to have the most detrimental effect on the polypeptide product? Group of answer choices a substitution of the first nucleotide of a GGG codon a substitution of the third nucleotide in an ACC codon an insertion of a codon a deletion of two nucleotides a deletion of a codonarrow_forward
