  • The proteome of a cell is the number of different proteins that a cell is able to produce.
  • The start codon is AUG which codes for the amino acid methionine (MET).
  • A codon is a group of three bases on mRNA that codes for an amino acid.
  • Stop codons signal the end of translation and result in the detachment of polypeptide chain from ribosome.
  • tRNA is more stable than mRNA because it has hydrogen bonding between complementary base pairs.
  • The function of tRNA is to carry specific amino acids to the ribosome
  • Transcription is the production of mRNA from DNA.
  • Translation is the production of polypeptides from the sequence of codons carried by mRNA.
  • Splicing removes introns and joins exons together to form mRNA.
