RNA and protein synthesis

• Two stages of protein synthesis

  Transcription and translation
• RNA

  A single polynucleotide stand containing uracil instead of thymine
• Messenger RNA (mRNA)

  Made during transcription

  Carries the genetic code from DNA to ribosomes to make a protein during translation
• Structure of mRNA

  A single polynucleotide strand

  Contains codons - group of three adjacent bases
• Transfer RNA (tRNA)

  tRNA is involved in translation since it carries the amino acids used to make proteins to the ribosomes
• Structure of tRNA

  A single polynucleotide strand that's folded into a clover shape

  Hydrogen bonds between specific base pairs

  Specific sequence of three bases at the one end - called the anticodon

  Amino acid binding side
