STAAR Day 4 DOL (DNA, Transcription/Translation)

How is the information for a specific protein carried on the DNA molecule?

• As a sequence of nucleotides (nitrogenous bases)

• In the double-helix shape of the condensed chromosome

• In the ratio of adenines to thymines

• As a pattern of phosphates and sugars

Different types of mutations can occur in DNA. The diagram represents a type of mutation. Which statement describes the mutation in the diagram?

• A silent mutation results in the insertion of a different amino acid

• A substitution occurs with the adenine base.

• A deletion of a cytosine base occurs.

• A base is inserted into one strand of the DNA

Students are modeling mRNA during the process of protein synthesis. Which answer choice correctly describes the model of the mRNA strand being transcribed?

• The mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine.

• The mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine.

• The mRNA strand is an exact copy of the DNA template strand; however, uracil instead of adenine is paired with thymine.

• The mRNA strand is an exact copy of the DNA template strand; however, uracil instead of thymine is paired with adenine.

Which of these is the correct amino acid chain produced from the DNA template strand:

3' TCC AAT GGC TTA TTT GCA 5'

• Arginine - Leucine - Proline - Asparagine - Lysine - Arginine

• Tryptophan - Phenylalanine - Leucine - Glycine - Asparagine - Phenylalanine

• Serine - Leucine - Proline - Asparagine - Lysine - Arginine

• Tryptophan - Phenylalanine - Leucine - Glycine - Asparagine - Serine

What is the purpose of this process?

• To replicate the DNA of an organism before cell division

• To assemble nucleotides in an mRNA chain along a DNA template

• To synthesize amino acids used to unzip strands of DNA and copy the genetic code

• To translate the genetic code into a specific sequence of amino acids
