DNA and RNA Review

In Eukaryotic cells, where is DNA ALWAYS located?

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

Which molecule holds ALL of an organisms' genes ALL the time?

• DNA
• RNA

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

Which of the following is true about RNA?

• It is temporary
• It can leave the nucleus
• It is single stranded and less stable than DNA
• All of these

Which of the following is the correct order of molecules?

• DNA -> RNA -> Proteins
• Proteins -> DNA -> RNA
• RNA -> DNA -> Proteins
• There is no specific order of these molecules
