RNA vs. DNA

Which sequence of DNA bases would pair with this partial strand
ATG TGA CAG

• ATG TGA CAG
• TAC ACT GTC
• GTA AGT GAC
• CAT TCA CTG

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids
• nucleotides
• fatty acids
• polysaccharides

Guanine bonds with ______________.

• Adenine
• Guanine
• Cytosine
• Thymine

In Eukaryotic cells, where is DNA ALWAYS located?

• Cytoplasm
• Nucleus
• Outside of the cell
• DNA is always moving around

Which of the following would most correctly describe DNA?

• Permanent (should never break down)
• Temporary (breaks down after it is read)

Which of the following is true of DNA?

• It can sometimes leave the nucleus
• It never leaves the nucleus
• It is portable
• It is temporary

Which of the following molecules holds the code for ONE gene at a time?

• DNA
• RNA

WHY must we use RNA if we already have genetic code in DNA?

• RNA is portable and can be read by the ribosome
• RNA is more accurate than DNA
• The cell needs a backup code and uses RNA
• DNA and RNA can be used interchangeably 

What happens to the RNA code when it leaves the nucleus?

• It remains as RNA forever
• It finds a ribosome and is read
• It leaves the cell
• It returns to the nucleus

Why do we care so much about making proteins in our cells?

• Proteins compose almost EVERYTHING in our cells
• If a protein is made incorrectly it will not work
• Proteins determine our physical traits
• All of these are correct
