DNA Structure and Protein Synthesis Quiz

What are the 2 major steps in Protein Synthesis?

• Translation and Transition

• Creation and Cremation

• Transcription and Translation

• mRNA and tRNA

Which RNA molecule carries amino acids?

• messenger RNA

• transfer RNA

• ribosomal RNA

• RNA polymerase

What happens during the process of transcription?

• tRNA is made in cytoplasm

• DNA is copied into the form of mRNA

• DNA replicates itself

• mRNA is used to bring in amino acids to the ribosome

What happens during the process of translation?

• Messenger RNA is made from DNA.

• The cell uses information from messenger RNA to produce proteins.

• Transfer RNA is made from messenger RNA.

• Copies of DNA molecules are made.

If the DNA code is A-T-G, what would it’s complementary strand of mRNA be

• U-A-G

• U-A-C

• T-U-C

• T-A-C

If the mRNA codon reads U-G-A, then the tRNA anticodon would be

• A-C-U

• A-C-T

• A-A-U

• U-C-T

Using the RNA codon chart, what amino acid does C-A-U correspond to?

• Glutamine

• Tyrosine

• Lucine

• Histidine

The amino acid Methionine is always the amino acid attached to the start codon. Using the RNA codon chart, determine the 3 letter start codon

• AUG

• UAG

• GUA

• AUC

Proteins are made up of _________.

• nucleotides

• RNA

• Amino acids

Each set of three nitrogenous bases that codes for an amino acid is known as a

• codon

• nucletoide

• protein

• RNA
