  • What is an Okazaki Fragment?
    are short sequences of DNA nucleotides
  • One of the 2 strands of DNA is used as a what strand to create a new strand of mRNA?
    Template Strand
  • What are the characteristics of the tertiary level of proteins?
    three dimensional shape of proteins
  • What is DNA Replication?
    DNA copies itself.
  • Give at least five examples of amino acids.
    Glycine, valine, alanine, phenylalanine, tyrosine, tryptophan, serine, cysteine, glutamine
  • What is RNA Polymerase?
    RNA Polymerase is an enzyme that makes/synthesizes mRNA in the same manner that DNA is duplicated.
  • What is a codon?
    Each 3 bases on mRNA are called codons. Each codon codes for 1 amino acid.
  • Where does Transcription occur?
    Transcription happens in the nucleus
  • Transcription always starts at a region called what?
    Transcription always starts at a region called the promoter.
  • What are segments of nucleotides located on the chromosomes that give specific instructions for a single trait?
    Genes are segments of nucleotides located on the chromosomes that give specific instructions for a single trait
  • DNA is coiled into strands, called what, which are found in the nucleus of Eukaryotes.
    DNA is coiled into strands, called chromosomes, which are found in the nucleus of Eukaryotes.
  • Where does Translation occur?
    Translation happens in the ribosome.
  • What are the characteristics of quaternary level of proteins?
    two or more chains of polypeptides
  • What is Translation?
    Translation: mRNA ---> Protein
  • What is the building block of a protein?
    Amino acids are the building blocks of protein
  • What is Transcription?
    Transcription: DNA ---> mRNA
  • WHy is DNA Replication called semi-conservative?
    because one half of the original strand is always saved, or “conserved.”
  • What are the characteristics of the primary level of proteins?
    arrangement of amino acids
  • What does DNA helicase do?
    DNA Helicase is an (enzyme) unwinds the DNA.
  • Translation requires which enzyme?
    RNA Polymerase
  • DNA is often coiled around proteins called what?
    DNA is often coiled around proteins called histones.
  • In DNAearth, C is married to G and in RNAland C is also married to G. A is married to T in DNAearth, but who is A married to in RNAland?
    A is married to U in RNAland
  • What is DNA Polymerase?
    adds the complementary nucleotides and binds the sugars and phosphates. DNA polymerase travels from the 3’ to the 5’ end. The DNA is called the template strand.
  • True or False: RNA is a single sided stranded.
    True. DNA is double stranded.
  • What is Messenger RNA (mRNA)?
    mRNA: It makes a mirror copy of a gene on the DNA strand in the nucleus.
  • What are the characteristics of the secondary level of proteins?
    α-helix and the ß-sheet.
