1. The Basics of DNA

2. DNA Deoxyribose sugar Phosphate bonds Nitrogen bases: (A, T, C, and G) A-T and G-C complementary pairing Double stranded (helix) Found only in nucleus

3. Genetic Code found in the order of the bases every 3 bases has 64 possible combinations 3 billion base pairs per cell

4. RNA ribose sugar phosphate bonds bases: A, U, C, and G single strand copy of one strand of DNA (except for U instead of T)

5. Transcription Process of copying RNA from DNA Copy leaves the nucleus and goes to ribosome Copy is called messenger RNA (mRNA) mRNA now has the genetic code also mRNA carries code in sets of three bases (codons)

6. Transfer RNA (tRNA) found at the ribosome tRNA has set of three bases (anticodon) that binds complimentary to the codons on the mRNA each carries a specific amino acid 20 different amino acids sets specific amino acid down at specific spot to make a chain of amino acids (protein or polypeptide) Translation

7. Proteins are made as the tRNA places the amino acids in a specific order tRNA is reading the code on the mRNA to determine the amino acid and order mRNA is a copy of DNA DNA is ultimate code for the proteins that make us work. Web 1 Web 2
