Protein Synthesis, RNA and Mutation

Which of the following shows the sequence genetic information takes to make a protein?

• DNA to RNA to Protein

• RNA to DNA to Protein

• Protein to DNA to RNA

• Protein to RNA to DNA

Genetic information stored in DNA is transferred to a molecule of mRNA in the ____________ during the process of ___________

• Cytoplasm, translation

• Cytoplasm, transcription

• Nucleus, translation

• Nucleus, transcription

The mRNA codons are read by a ___________ and translated into an amino acid sequence during the process of ___________.

• Nucleus, translation

• Nucleus, transcription

• Ribosome, translation

• Ribosome, transcription

There are only 20 amino acids listed in the codon chart, so how can thousands of different proteins be made in your body?

• The size of amino acids is different

• The number and sequence of amino acids are different in each unique protein

• Chemical composition of amino acids can be different

• The electrical charges of amino acids are different

The chart below shows some codons and their corresponding amino acids. A sequence of DNA in a gene is TAC CGC ATA ATC. Follow the processes of transcription and translation to form an amino acid sequence.

If a mutation occurred to the DNA sequence TAC CGC ATA ATC and the new DNA strand reads: TAC CGG AGA ATC. What would be the new amino acid sequence?

What type of mutation occurs when a nitrogen base is switched with another base?

• Insertion

• Deletion

• Substitution

What do chains of amino acids make?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acid

Put the following terms in order of progression:

• DNA, Amino Acid, mRNA, Protein, Trait

• Amino Acid, Protein, DNA, mRNA, Trait

• Protein, Amino Acid, DNA, Trait, mRNA

• DNA, mRNA, Amino Acid, Protein, Trait

What are the different gene codes on the mRNA called

• Protons

• Codons

• Proteins

• Nucleotides
