Which phrase best describes translation?

• process in which tRNA is involved in making proteins
• catalyzes bonds between amino acids
• produces RNA from DNA molecules
• recycles tRNA molecules for reuse

In comparison to a DNA strand, a 

• mRNA strand is shorter and single stranded
• mRNA strand is longer and single stranded
• mRNA strand is shorter and double stranded
• mRNA strand is longer and double stranded

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

What is the first step in DNA replication?

• The paired bases release many types of proteins.
• New bases are built by the original strands.
• The DNA is cut into pieces using polymerase enzymes.
• The double helix unwinds, and each side is a template for a new strand.

Which of these bases does not exist in RNA?

• C
• T
• U
• A

Guanine always hydrogen bonds with Cytosine. This is an example of:

• Contemplation Proclamation Perspiration
• Confusatory Base Maturation
• Compligatory Nitrogenase
• Complementary Base Pairing
