• DNA is made of proteins and RNA is made of lipids.

What are genes, and what do they do?

• Genes are section of a chromosome that contain instructions for building protein.

• A gene is a form of energy that powers cells.
• A gene is a type of virus that infects organisms.

Which type of RNA carries the sequence of bases that determines the order of amino acids in a protein from the nucleus to the cytoplasm?

• 
  

• Small nuclear RNA (snRNA)
• Ribosomal RNA (rRNA)
• Messenger RNA (mRNA)
• Transfer RNA (tRNA)

Which type of RNA is a major component of the structure at which protein synthesis occurs, the protein “factory.”

• 
  

• Ribosomal RNA (rRNA)
• Micro RNA (miRNA)
• Messenger RNA (mRNA)
• Transfer RNA (tRNA)

Which choice best defines transcription?

• The process of converting RNA into DNA
• The process of creating a protein from RNA
• The making of an RNA molecule from a DNA strand, by pairing bases of RNA nucleotides with the complementary bases in DNA
  

• The process of duplicating a protein's DNA sequence

Where in the cell does transcription take place?

• nucleus
• endoplasmic reticulum
• mitochondria
• cytoplasm
