Flashcards in biology ch 12 Deck (17)
monomers that make up DNA
two strands wound around each other
THE PROCESS OF MAKING COPIES Of DNA
enzyme responsible for DNA replication
functions of nucleic acid
they're macromolecules that store or transmit RNA - genetic information
three different pars of a nucleotide
1. 5 carbon sugars
2. phosphate group
3. nitrogenous bases
4 possible nitrogenous bases that a nucleotide can have for DNA.
ademne, thymine, cytosine, and guanine
Which of the nitrogenous bases are pyrimidines?
thymine and cytosine
Know which nitrogenous base pairs bind together according to complementary base pairing; Understand how this is supported by Chargaff’s rules.
put everything together
worked out the math
took x-ray pictures of what DNA structures looked like
what the dna is shaped like - twisted ladder
discovered two rules that helped lead to the discovery of the double helix structure
discovered that the amounts of adenine and thymine in DNA were roughly the same, as were the amounts of cytosine and guanine
