Which of these if the correct amino acid chain produced from the DNA template strand?

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

• Tryptophan - Phenylalanine - Leucine - Glycine - Asparagine

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

• Tryptophan - Valine - Leucine - Glycine - Asparagine - Serine

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

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

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

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

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

Picture shows a model of a biological process.

What is the purpose of the process?

• To replicate the DNA of an organism before cell division

• To assemble nucelotides in a 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

The initial steps in gene expression are modeled in the pcture. Double-stranded DNA first unwinds into two strands.
