    • How did we know that genes are composed of DNA
      Hershey-Chase experiment
    • a principle in molecular biology that describes the relationship between the four nitrogenous bases that make up DNA
      Chargaff's rule
    • how many percent is adenine and thymine in dna
      31%
    • Guanine and Cytosine, how many percent
      19%
    • what does ATCG stands for
      Adenine Thymine Cytosine Guanine
    • Showed DNA is a double helix. It shows some portion of the helix is repeated many times
      Franklins X-Ray Diffraction Data
    • Model of DNA out of wire
      The deoxyribose sugar-phosphate backbone make up the sides of the ladder.
      The nitrogenous bases make up the rungs of the ladder.
      The Watson and Crick Model
    • the process of making an identical copy of the parent cell’s DNA.
      DNA replication
    • proper order of chargaff's rule
      ATCG
    • Thymine is replaced to what in RNA
      Uracil
    • 1st: It opens up the DNA at the replication fork.
      Helicase
    • 2nd: it coat the DNA around the replication fork to prevent rewinding of the DNA.
      Single-strand binding proteins
    • 3rd: works at the region ahead of the replication fork to prevent supercoiling.
      Topoisomerase
    • 4th: synthesizes RNA primers complementary to the DNA strand.
      Primase
    • 5th: It extends the primers, adding on to the 3' end, to make the bulk of the new DNA.
      DNA polymerase III
    • 6th: They are removed and replaced with DNA by DNA polymerase I.
      RNA Primers
    • 7th: The gaps of DNA fragments are then sealed by
      DNA ligase
    • It has Single strand and Sugar: ribose
      Ribonucleic acid(RNA)
    • Produced in the nucleus; where DNA genes are transcribed
      Messenger RNA (mRNA)
