Ms. Doshi Chapters 2.19-2.21
Nucleic Acid Terms nucleic acids -macromolecules that store information -made up of nucleotides -2 types: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) Nucleotides (3 parts) -sugar + phosphate group + nitrogen-containing base DNA bases -adenine (A), guanine (G), cytosine (C) or thymine (T) RNA bases -adenine (A), guanine (G), cytosine (C), or uracil (U)
2.20 DNA -structure is a double helix -in DNA (bases form like this): adenine always bonds with thymine (2 H bonds) guanine always bonds with cytosine (3 H bonds)
Questions Chapter 2 Review in Textbook MCQ: 1-20 pp. 77-79 And do these questions: • Nucleic acids are made up of ______. • What are the parts of a nucleotide? • What are the DNA bases? • What are the RNA bases? • What binds with guanine? • What binds with uracil? • What are the number of H bonds between adenine and thymine? • What are the 3 main differences between DNA and RNA? • DNA is a _________ helix. • What does DNA stand for?
