The cell cycle consists of Mitosis and Interphase. Interphase consists of 'G' 1, 'S' & 'G' 2. 'G' 1 is 99% of the cell's life, in which proteins are made:
- DNA unwinds the hydrogen bonds break. One side of the DNA is the coding strand the other is the template strand. We need a copy of the coding strand.
- The 'm' RNA is built up against the template strand, Uracil being paired with Adenine, Polymerase joins the nucleotides together.
- 'm' RNA leaves the nucleus (Transcription ends, Translation starts).
- Ribosome clamps around the 'm' RNA 9 a time.
- 't' RNA brings an amino acid with a specific triplet. The triplet on 't' RNA is the Codon and the triplet on the 'm' RNA is the Anticodon.
- Ribosomes fuse the amino acids together forming peptide bonds. There are normally several ribosomes on one chain.
- Protein is packaged by the Golgi Apparatus
- Sometimes ribosomes docks onto 'R' 'E' 'R' and feeds protein inside it. Vesicle forms and is then taken to Golgi Apparatus where…
