Assembling a protein molecule from amino acids Amino acids are small molecules found in the foods we eat or are produced in our cells. Happens at the ribosomes transcription DNA → RNA is called transcription. translation RNA → Protein is called translation.
1) The DNA’s sequence codes to produce messenger RNA (mRNA) 2) The mRNA leaves the nucleus and attaches to a ribosome in the cytoplasm 3) Transfer RNA (tRNA) brings amino acid molecules to the ribosome that correspond to the sequence of the code 4) Amino acids bond together to form polypeptides, that bond together to make proteins
Complex machinery that controls protein synthesis. 2 subunits One catalyzes the peptide bond formations The other binds the mRNA to the tRNA
Single-stranded Still made of nucleotides that have a phosphate, a sugar, and a nitrogen base Adenine, Uracil, Guanine, Cytosine
