What would happen if a chemical interfered with the ability of RNA polymerase to bind to a DNA molecule?

• Transcription would proceed, and a protein would be produced.
• The DNA molecule would replicate itself.
• The RNA polymerase would cut the DNA molecule in half.
• Transcription would not take place, and the protein would not be produced.

_______ is to transcription as ________ is to translation.

• mRNA / Amino Acid Chain
• Amino Acid Chain / mRNA
• Ribosome / Nucleus
• mRNA / tRNA

Translation is performed by:

• Ribosomes 
• Mitochondria
• Golgi Bodies
• Endoplasmic Reticulum 

Translation in eukaryotes occurs:

• Outside of the Nucleus

• Inside of the Nucleus

what is an operon?

• a part of a ribsome
• a part of a Rna
• a unit made up of linked genes that code for proteins needed to do a specific task
• needed for dna replication

A protein that binds to the operator and blocks the RNA polymerase

• regulator
• repressor
• activator
• corepressor

The "on/off" switch for an operon is called the

• promoter
• repressor
• operator
• gene

What is the name of the stretch of DNA where RNA polymerase binds?

• operator
• promoter
• enhancer
• origin
