RNA

• What is RNA a polymer of?

  Nucleotide
• What are the components of a nucleotide in RNA?

  Ribose, nitrogenous base, phosphate group
• Which nitrogenous bases are found in RNA?

  Adenine, guanine, cytosine, uracil
• What base does RNA have instead of thymine?

  Uracil
• How does the length of RNA compare to DNA?

  RNA is shorter than DNA
• What is the primary function of RNA?

  Copy and transfer genetic code to ribosome
• What is rRNA?

  Ribosomal RNA
• What role does rRNA play in ribosomes?

  Makes up the bulk of ribosomes
• What is the difference between DNA and RNA bases?

  DNA has thymine, RNA has uracil
• What sugar does DNA contain compared to RNA?

  DNA has deoxyribose, RNA has ribose
• How do the sizes of DNA and RNA polymers compare?

  DNA is larger than RNA
• What is the structure of DNA compared to RNA?

  DNA is double stranded, RNA is single stranded
• What is mRNA?

  Messenger RNA
• Where is mRNA created?

  In the nucleus
• What does mRNA carry to the ribosome?

  Copy of the genetic code of one gene
• Why can't DNA leave the nucleus?

  It's too large and risks damage
• Why is mRNA short-lived?

  It is only needed temporarily
• What do every three bases in mRNA code for?

  A specific amino acid

  Transfer amino acids to ribosome
• How do specific amino acids attach to tRNA?

  By complementary bases to mRNA
• What are anticodons?

  Complementary to codons on mRNA
• What is located at the top of tRNA?

  Amino acid attachment site
