RNA

• Label this nucleotide

  A) phosphate group

  B) pentose sugar (ribose)

  C) nitrogenous base

  
• What are the bases in RNA?

  Guanine, cytosine, adenine, uracil
• RNA molecules are single, not double stranded. They are also shorter than DNA
• What is the pentose sugar in RNA?

  Ribose
• What are the nitrogenous bases in RNA?

  Purines: adenine and guanine

  Pyrimidines: cytosine and uracil
• How many strands does RNA have?

  1, it is single stranded
• What are the lengths of the different types of RNA?

  tRNA and rRNA are both short

  mRNA varies but it is still shorter than DNA
