Identify the correct sequence of molecules, as a gene goes from coded information in the nucleus, to the product the cell wants to make at the ribosome.

• DNA -> messenger RNA -> transfer RNA -> protein

• DNA -> transfer RNA -> messenger RNA -> protein

• DNA -> transfer RNA -> protein -> messenger RNA

• Protein -> messenger RNA -> transfer RNA -> DNA

Unlike DNA, RNA contains

• adenine.

• uracil.

• phosphate groups.

• thymine.

During TRANSCRIPTION, a DNA strand that has the bases CTAGGT produces a strand with the bases

• GAUCCA

• GATCCA.

• AGCTTG.

• GAGCAC.

What type of RNA acts like a delivery truck, delivers amino acids to the ribosome for protein synthesis, and then leaves empty again, to go collect another amino acid?

• messenger RNA

• ribosomal RNA

• transfer RNA

• mitochondrial RNA

You are a world famous scientist who has discovered the gene that codes for a specific protein used to dissolve blood clots in humans. You are about to mass produce this gene for medical science. What must you know about this specific protein in order to begin gene production?

• the number of adenine bases present

• the shape of the protein molecule

• the amino acid sequence of the protein

• the nucleotide sequence of the entire human genome
