  1. 3. a chain of amino acids bonded together before the folding of the protein occurs.
  2. 9. the type of chemical bond that holds together lipid monomers. Hint: it is the name of a special kind of covalent bond, specific to lipids.
  3. 10. a large molecule composed of monomers
  4. 11. the simplest form of a carbohydrate. Glucose is a good example of one.
  5. 14. A sub-unit (single unit) of a polymer
  6. 16. general term for a large carbohydrate; hundreds to thousands of monosaccharides bonded together
  7. 19. the monomers of protein. A molecule made of an asymmetric carbon covalently bonded to hydrogen, amino group, carboxyl, and R group
  8. 23. most common monosaccharide
  9. 24. the type of chemical bond that holds together amino acids.
  10. 26. lipids that exist as a liquid at room temp and has 1 or more double bond (C=C)
  11. 28. a relatively small carbohydrate that consists of 2 monosaccharides bonded together
  12. 30. a lipid that is composed of 1 glycerol + 2 fatty acids + phosphate group; also a component of the cell membrane
  13. 31. the type of "bond" or attraction found in between bases in DNA
  14. 32. the level of protein structure resulting from interactions among 2 or more polypeptides.
  15. 33. the level of protein structure determined by a unique sequence of amino acids
Down
  1. 1. one of the three parts of the DNA monomer; This structure makes the monomer unique from the other.
  2. 2. a lipid that is composed of 1 glycerol + 3 fatty acids
  3. 4. the name of the sugar in the DNA molecule
  4. 5. the type of covalent bond found in the backbone of DNA
  5. 6. how many times a carbon atom bonds to other atoms
  6. 7. a segment of DNA that codes for traits. The length of each segment varies.
  7. 8. the level of protein structure caused by the irregular folding of a polypeptide due to bonding between R groups.
  8. 12. describes the orientation of the two strands of DNA
  9. 13. the nucleotide complimentary to guanine
  10. 15. a chemical reaction resulting in the breakdown of a polymer using water
  11. 17. the type of chemical bond that holds together carbohydrate monomers
  12. 18. the monomers of DNA and RNA
  13. 20. lipids that exist as a solid at room temp and has only single bonds (C-C)
  14. 21. the overall shape of DNA, resembling a twisted ladder.
  15. 22. The 3'-->5' DNA complimentary to 5'-TTAAGGCTA-3'
  16. 25. lipids that serve as coatings for plant parts and as animal coverings to help prevent desiccation or drying out
  17. 27. the level of protein structure caused by repeated folding of the polypeptide backbone. The 2 types are the alpha helices and beta pleated sheets.
  18. 29. A chemical reaction resulting in a bond and is created through the loss of water
