protein synthesis Flashcards
protein synthesis
Making new proteins (like hormones and enzymes) for the body. Protein Synthesis occurs in two steps and in two areas of the cell. This happens because DNA cannot leave the nucleus of the cell.
transcription
AKA writing mRNA occurs in the nucleus of the cell
translation
translating of mRNA for amino acids occurs using ribosome in the cytoplasm of the cell
steps of transcription
part of DNA unzips & creates mRNA with the help of RNA polymerase, thymine is replaced by uracil, and only one side of DNA is transcribed into mRNA
steps of translation
with the help of a ribosome, mRNA is translated, the polypeptide chain is created where each amino acid is joined by a peptide bone = protein
