Protein Synthesis Quiz

Write the complementary DNA for the following: GTCAACGCAGGT

Write the correct mRNA codons for the following DNA: CCATATGCATTC

Write the complementary tRNA anti-codons for the following mRNA: UUAGCUAGGCCU

Match the nitrogenous bases with their nucleic acids:

• DNA only

• Uracil

• RNA only

• Cytosine and Guanine

• Both DNA and RNA

• Thymine

Put the central dogma of biology in the correct order of the flow of genetic information.

• Protein

• DNA

• RNA

Place the steps of translation in order from beginning to end.

• tRNA molecules bring amino acids to the rRNA according to the mRNA codons

• Amino acids are joined together to form a polypeptide

• The polypeptide grows with each amino acid until it is completed

• mRNA that left the nucleus travels to the rRNA in the cytoplasm

Place the steps of transcription in order from beginning to end.

• RNA polymerase adds complementary RNA nucleotides

• Newly synthesized mRNA is formed

• DNA is separated into two strands

• mRNA exits the nucleus through the nuclear pore into the cytoplasm
