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 thymine 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.

What is the purpose of the process shown in the model?

• 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

What is the purpose of this cellular process?

• Preserving genetic information for future generations

• Deleting the information in the sequence produced from the DNA template

• Transcribing information in the DNA sequence for use by the cell

• Producing more nucleotides for the DNA sequence
