protein synthesis

• summarise transcription in one sentence

  the process of copying of a single gene of DNA to mRNA
• where does transcription take place

  nucleus
• 3 differences between mRNA and DNA

  1. mRNA is shorter than DNA
  2. mRNA is single-stranded while DNA is double-stranded
  3. mRNA contains Uracil (U) where DNA contains Thymine (T)
• where does mRNA go once it has been transcribed

  ribosomes
• summarise translation in one sentence

  the process by which a ribsome combines amino acids together to form a protein, using the instructions of mRNA
• how many bases are needed to code for one amino acid

  3
• whats the function of a ribosomes

  to carry out protein synthesis (assemble amino acids to form a protein)
• what is a polypeptide

  chain of amino acids
