Mastery Check 3.1.2

Which is the process of using a DNA template to make mRNA?

• translation

• replication

• transcription

• differentiation

Which best describes the role of mRNA in protein synthesis?

• mRNA brings amino acids to the ribosome where they are connected to construct a protein.

• mRNA forms the peptide bonds connecting amino acids together to construct a protein.

• mRNA decodes the sequence of tRNA into the amino acids used to construct a protein.

• mRNA brings the code of DNA to the ribosome where it is used to construct a protein.

Which is a way that RNA differs from DNA?

• uracil base

• 3-stranded

• no phosphate group

• connected by peptide bonds

A segment of the DNA from a chimpanzee has the sequence: TAC GAA GCA. Which mRNA would be transcribed from this segment of DNA?

• GCA TCC TAC

• AUG CUU CGU

• ATG CTT CGT

• GCA UCC UAC

Which best describes the process of translation?

• Translation occurs within the nucleus.

• Translation involves copying a DNA strand.

• An mRNA strand is produced by the process of translation.

• A growing protein chain is produced by the process of translation.

Use the codon chart below to answer the question. Which shows the translated amino acid chain for the code AUG GCC UAC?

• Methionine, Alanine, Tyrosine

• Isoleucine, Alanine, Tyrosine

• Methionine, Alanine, Stop

• Isoleucine, Alanine, Stop

What is the function of transfer RNA?

• It is a part of the ribosome.

• It delivers the correct amino acid to the ribosome.

• It bonds to other RNA molecules, leading to their destruction.

• It carries the information coding for the amino acid sequence of a protein.

How are the amino acids linked together during translation?

• by creating peptide bonds

• by creating hydrogen bonds

• by creating covalent bonds

• by creating phosphate bonds

A segment of mRNA contains the following codons AUG CAA GGU GAG. Which are the complementary tRNA anticodons?

• TAC GTT CCA CTC

• UAC GUU CCA CUC

• UAC GUU CCU GUG

• AUG CAA GGA GAG

Which is affected by the order of amino acids?

• The type of proteins produced.

• The type of nucleotides produced.

• The type of peptide bonds produced.

• The type of phosphate group produced.
