Protein synthesis

By ZeeL16

  • An enzyme attaches to the DNA molecule at the gene of interest.

  • The two strands of DNA separate at that location.

  • Complementary RNA nucleotides bond to the nitrogenous bases on one of the separated DNA strands.

  • The chain of RNA nucleotides forms a single-stranded molecule of RNA by using the DNA strand as a template.

  • The chain of RNA nucleotides forms a single-stranded molecule of RNA by using the DNA strand as a template.

  • The two DNA strands rejoin.

  • The mRNA attaches to a ribosome, which contains proteins and ribosomal RNA (rRNA). The function of ribosomes is to assemble proteins according to the genetic message.

  • Another type of RNA, transfer RNA (tRNA), brings amino acids to the ribosome in the order specified by the codon sequence on the mRNA.
