DNA+HW+MA


 * Define:
 * Complementary paired bases: Hydrogen bonding holds the bases together: A pairs with T and G pairs with C.
 * Template: During replication the double-stranded structure of DNA allows each of original strand to serve as a template for the formation of a complementary new strand.
 * Mutation: a permanent change in the sequence of bases that can possibly cause a change in phenotype and introdouce vaariability.
 * Messenger RNA: Carries genetic information from DNA to the ribosomes in the cytoplasm where protein synthesis occurs.
 * DNA Replication: The process of copying a DNA helix.
 * Transcription:A strand of MRNA forms that is complementary to a portion of DNA. The mRNA that is formed is a transcript of a gene.
 * Translation: A sequence of mucleotides is translated into the sequence of amino acids. Make proteins.
 * Codon: Each three letter unit of an mRNA molecule.

1) How does the structure of DNA allow it to be duplicated. 2) How is the structure of RNA similiar to, but also different from DNA(long answer). 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?
 * It has a double helix that can be unzipped and copied.
 * Both DNA and RNA:
 * are made of nucleotides and nucleic acids
 * they have sugar-phosphate component
 * Different;
 * Dna is double helix
 * Rna is single stranded
 * CGGUAGACC
 * GCCAUGACC
 * A protein is a sequence of amino acids.
 * Proteins determine the structure and function of cells in the body.
 * Isoleucine
 * Alanine
 * Tryotophan
 * Because all living things have a genetic code.
 * Transcription occurs in the double helix of DNA. This results in a DNA strand.
 * Translation occurs in the cytoplasm. In this process tRNA brings amino acids to the ribosomes and this forms polypeptide chains.
