DNA and RNA Replication Review

You may use your notes to answer the following questions. You may NOT use the internet to search for these answers.

DNA Structure Review

• DNA consists of two molecules that are arranged into a ladder-like structure called a Double Helix.

• DNA is a molecule classified as a Nucleic acid. It is made up of millions of tiny subunits called Nucleotides. 

• Each nucleotide consists of: Phosphate group Pentose sugar Nitrogenous base

Multiple Choice

• Adenine - Guanine

  Cytosine - Thymine

• Thymine - Adenine

  Cytosine - Guanine

• Adenine - Uracil

  Thymine - Cytosine

• Adenine - Uracil

  Cytosine - Guanine
