Term | Definition |
nucleic acid | RNA and DNA are this type of DNA biomolecule |
nucleotide | phosphate, sugar, and base makes up the DNA ladder |
deoxyribose | the 5-carbon sugar found in DNA |
ribose | the 5-carbon sugar found in RNA |
purines | adenine and guanine |
pyrimidines | cytosine and thymine |
adenine (A) | bonds with thymine(T) in DNA and bonds with uracil(U) in RNA |
thymine (T) | this base is only found in DNA and bonds with adenine (A) |
cytosine (C) | bonds with guanine (C) |
guanine (G) | bonds with cytosine (C) |
uracil (U) | this base is only found in RNA and bonds with adenine (A) |
base pairing | A bonds with T or U and G bonds with C Good Cats Always Together Good Cats Always United |
Double helix | shape of DNA |
hydrogen bonds | found between the base pairs and holds the bases together |
backbone of DNA | phosphate-sugar |
semiconservative replication | another name for DNA replication in which one old and one new strand is made |
DNA replication | DNA is copied into 2 identical strands-unzips,base pairs, join nucleotides |
Double helix | shape of DNA molecule |
gene | segment of DNA |
histones | A protein in which DNA coils around |
chromosomes | contains the genetic information in DNA |
DNA Helicase | Enzyme that unzips the DNA ladder |
DNA Polymerase | Enzyme that adds new bases to the replicating DNA |
DNA ligase | Enzyme that joins the hydrogen bonds between the bases at the end of replication |
DNA fingerprint | made from gel electrophoresis and used to solve crimes and determine parental relationships |
