Define complementary paired bases- hydrogen bonding between particular bases. T pairs with A and G pairs with C. Rna U pairs with A and G with C template- pattern or guide used to make copies parental strands of DNA reserves as a guide for the production of daughter DNA strands and DNA also serves as a guide for the production of messenger RNA mutation- alteration in chromosome structure or number and also an alteration in a gene due to to a change in DNA composition messenger RNA- Type of RNA formed from a DNA strand template that bears coded information for the amino acid sequence of a polypeptide. DNA replication- synthesis of a new DNA double helix prior to mitosis and meioses in eukaryotic cells and during prokaryotic fission in prokaryotic cells. transcription- process whereby a BNA strand serves as a template for the formation of mRNA translation- process whereby ribosomes use the sequence of codons in mRNA to produce a polypeptide with a particular sequence of amino acids. codon- three base sequence in mRNA that causes the insertion of a particular amino acid into a protien or termination of translation.

Questions 1. How does the structure of DNA allow it to be replicated? 2. How is the structure of RNA similar to, but also different from DNA? (THIS IS A LONG ANSWER SEE TABLE 21.1)
 * it is formed like a ladder which makes it easy to replicate and divide evenly.

3. If a strand of DNA was GCCATGACC what would the complementary DNA strand be? 4. If a strand of DNA was GCCATGACC what would the complementary mRNA strand be? 5. What is the structure of a protein? 6. What functions do proteins perform? 7. If a mRNA had the codon sequence AUU GCG UGG, name the three amino acids that would be linked. 8. What evidence with respect to DNA suggests that all living things are related and share a common ancestor? 9. Where does transcription occur and what is the product? 10. Where does translation occur and what is the product?
 * CGGTACTGG
 * CGGUACUGG
 * the sequence of amino acids.
 * proteins help the muscles strong. it is also responsible for the red color in the blood.
 * TAA CGC ACC
