Nucleic Acids Super Clutch Flashcards

  1. Like proteins and carbohydrates, nucleic acids are ___
    polymers
  2. Each nucleotide has three
    parts:
    nitrogenous base, phosphate group, a five-membered cyclic monosaccharide
  3. they are cyclic compounds with at least one
    nitrogen atom in the ring structure
    heterocyclic amines
  4. The five-carbon sugar in RNA is
    ribose
  5. the sugar in DNA is
    2’-deoxyribose
  6. A molecule composed of either ribose or deoxyribose and one of the five nitrogenous bases
    found in DNA and/or RNA is called a
    nucleoside
  7. There are two types of nitrogenous bases:
    purines and pyrimidines
  8. Purines
    Adenine and Guanine
  9. Pyramidine
    Cytosine, Thymine and Uracil
  10. are the building blocks of nucleic acids; they are the monomers of the DNA and RNA
    polymers
    Nucleotides
  11. A nucleotide with the sugar ribose is a
    ribonucleotide
  12. a nucleotide having the sugar 2’-deoxyribose is a
    deoxyribonucleotide
  13. The covalent bond between the sugar and the phosphoryl group is a
    phosphoester bond
  14. plays an essential role as a source of
    biochemical energy, which is released during its conversion to adenosine diphosphate (ADP).
    Adenosine triphosphate (ATP)
  15.  A single strand of DNA is a polymer of nucleotides bonded to one another b___
    • 3’-5’ phosphodiester
    • bonds
  16. One noncovalent attraction that helps maintain the double helix structure is ______
    • hydrogen bonding
    • between the nitrogenous bases in the center of the helix
  17. are pieces of DNA that carry the genetic instructions, or genes, of an organism
    Chromosome
  18. The complete set of genetic information in all the chromosomes of an organism is called the
    genome
  19. are organisms with a simple cellular structure in which there is no true nucleus
    surrounded by a nuclear membrane and there are no true membrane bound organelles
    Prokaryote
  20. are organisms that have cells containing a true nucleus enclosed by a nuclear
    membrane
    Eukaryotes
  21. Adder’s Tongue fern have ___ chromosomes
    631
  22. The first level of structure of a chromosome is the
    Nucleosome
  23. Incubation of DNA at pH3
    causes selective removal of the purine bases, resulting in a derivative called
    apurinic acid
  24. The higher the G + C content of a DNA molecule,
    the higher the melting temperature
  25. -Discovered by Watson and Crick, is right-handed (natural DNA) and consists of 10 bps per
    turn of the helix.
    - most stable dna structure
    B-DNA
  26. This form is favored in many solutions that are relatively devoid of water or when DNA is
    partially dehydrated. The DNA is still arranged in a right-handed double helix, but the helix is
    wider and the number of base pairs per helical turn is 11
    A-DNA
  27. his form is a more radical departure from the B structure; the most obvious distinction is
    the left-handed helical rotation. There are 12 base pairs per helical turn
    Z-DNA
  28. is a word, phrase, or
    sentence that is spelled identically read either forward or backward;
    A palindrome
  29. When the inverted repeat occurs within each individual strand of the DNA, sequence is
    called a
    mirror repeat
  30. When only a single DNA (or RNA) strand is involved, the structure is called
    a hairpin
  31. When both strands of a duplex DNA are involved, it is called a
    cruciform
  32. As the DNA is heated and the strands separate, the wavelength of absorption does not change, but the
    amount of light absorbed increases This effect is called
    Hyperchromicity
