  • Q1
    nucleic acid that contains the sugar deoxyribose, double helix, nitrogen bases A T C G, NEVER leaves the nucleus
    DNA (deoxyribonucleic acid)
    30s
  • Q2
    single-stranded nucleic acid that contains the sugar ribose, nitrogen bases A U C G, Can be found in the nucleus, the cytoplasm, or the ribosomes
    RNA
    30s
  • Q3
    monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base
    Nucleotide
    30s
  • Q4
    RNA molecule, complementary to the original DNA strand, that carries instructions from the DNA in the nucleus for the assembly of amino acids to the rest of the cell (ribosomes specifically) so that proteins/traits can be made
    mRNA (messenger RNA)
    30s
  • Q5
    type of RNA molecule that transfers amino acids to ribosomes during protein synthesis
    tRNA (transfer RNA)
    30s
  • Q6
    type of RNA that makes up the major part of ribosomes
    rRNA (ribosomal RNA)
    30s
  • Q7
    three-nucleotide base sequence on messenger RNA that codes for a single amino acid
    codon
    30s
  • Q8
    a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA.
    anticodon
    30s
  • Q9
    decoding of a mRNA message into a polypeptide chain of amino acids (protein) from codons; Takes place in the cytoplasm/ribosomes
    translation
    30s
  • Q10
    process in which part of the nucleotide sequence of DNA is copied into a complementary sequence in mRNA; Takes place in the nucleus only. (DNA --> RNA)
    transcription
    30s
  • Q11
    a small organelle in the cell where proteins are assembled
    ribosome
    30s
  • Q12
    structure that contains the cell's genetic material (DNA) and controls the cell's activities
    nucleus
    30s
  • Q13
    A change or mistake in the DNA sequence--There are a variety of different types; Some are harmful, but some are not; Without them, we would have no genetic variation
    mutation
    30s
  • Q14
    A type of frameshift mutation when a base is removed from the sequence of nitrogen bases
    deletion mutation
    30s
  • Q15
    Mutation where one or more bases are added to the DNA sequence
    insertion mutation
    30s
