Process inside the nucleus when the DNA code is "copied" as an mRNA molecule forms
Genetic material of he cell that carries the chemical "blueprint" of the body (2 words)
Deoxyribonucleic Acid
A nucleic acid found in the cytoplasm that is crucial to protein sysnthesis (2 words)
Ribonucleic Acid
One pair of tiny cylinders in the centrosome of a cell
A beadlike structure that attaches one chromatid to another during the early stages of mitosis
Condition in which cells change in orientation to each other and fail to differentiate into specialized cell type
Synthesis of a protein in cytoplasm by ribosomes
Amino acids of the nearly 100 found in nature are used to build body protein. Proteins are used in the formation of:
  • Hormones
  • Enzymes
  • Plasma proteins
  • Muscle proteins
  • Hemoglobin
  • Most cell membranes
Arrange the phases of mitosis in the correct sequence:
1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telephase
Nucleic acids are composed of units called nucleotides that have three parts. The nucleotides for DNA are:
  • Sugar (Deoxyribose)
  • Phosphate group (PO4)
  • Bases--
    • -Adenine (A)
    • -Thymine (T)
    • -Cytosine (C)
    • -Guanine (G)
  • What is the system of bonding known as complementary base pairing?
    • Adenine can only pair with thymine (A-T).
    • Cytosine can only pair with guanine (C-G).
    RNA is also a nucleotide that is composed of three parts:
    • Sugar (ribose)
    • Phosphate group (PO4)
    • Bases--
      • -Cytosine (C)
      • -Guanine (G)
      • -Adenine (A)
      • - Uracil (U)
    DNA directs the function of each protein cell
    True. In addition to carrying genetic code, DNA also directs the function of cellular proteins
