RNA structure

• What does RNA stand for?

  Ribonucleic acid
• What sugar is in RNA?

  Ribose
• How many strands does RNA have?

  1
• What are the nitrogenous bases of RNA?

  Adenine,Cytosine,Guanine,Uracil
• Where is RNA found?

  Cytoplasm and Nucleus (As transcription occurs, it moves out of the nucleus into the cytoplasm)
• What are the functions of RNA?

  • Take DNA and turn it into proteins
  • Puts DNA to work by making a disposable copy of it
• How is RNA made?

  Transcription (Synthesized from split DNA)
• What are the types of RNA?

  • mRNA->carries copies of instructions for assembly of amino acids into proteins from DNA to the rest of the cell.
  • rRNA->makes up a major part of ribosomes
  • tRNA->transfers amino acids to ribosomes during protein synthesis
• Whats ribose?


  A sugar molecule that contains an OH- (hydroxide)
• What's transcription?

  the process of copying DNA into RNA
• Where does transcription occur?

  in the nucleus of eukaryotes
• Uracil replaces the thymine in RNA
• During transcription DNA is split. This is easy because of the weaker hydrogen bonds. The RNA is synthesized from 1 DNA strand (doesn't matter which one).
• What part of RNA is this?

  Phosphate

  
• What part of RNA is this?

  Nitrogen base

  
• What part of RNA is this?

  Ribose (sugar)

  
• The order of transcription is DNA-RNA-Proteins
• RNA makes proteins, proteins make up everything so RNA is very important.
