Essay on DNA Replication

Page 1

RNA synthesis

- DNA unzips/hydrogen bonds broken

- Enzymes and/or ATP needed

- RNA nucleotides align with bases of DNA

- Base pairings A-U, C-G, T-A, G-C

- Nucleotides bonded through sugar phosphate bonds

- mRNA transcribed/copied from DNA

Protein Synthesis

- mRNA passes out from the nucleus and attaches to ribosome

- tRNA's transport amino acids to ribosome

- Specific tRNA for each amino acid

- Triplets of bases on mRNA form codons OR triplets of tRNA form anti-codons

- Anti-codons/triplets of bases of tRNA match to the codons on mRNA

- Amino acids bond by peptide bonds
