  • 1

    Almost every cell in our bodies has genetic material in the form of

    DNA

  • 2

    DNA, the primary genetic material of living organisms, stores genetic information in the sequences of its

    Nucleotides

  • 3

    aid in DNA packaging.

    Positively charged histone proteins

  • 4

    Interphase DNA is found in the form of

    Chromatin

  • 5

    a complex of DNA and proteins

    Chromatin

  • 6

    Chromatin in dispersed inside the ----------- during interphase.

    Intact cell nucleus

  • 7

    Chromatin will sometimes need to further condense into a highly coiled and compact structure. This highly condensed form of DNA is known as a

    Chromosome

  • 8

    Humans have individual chromosomes.

    46

  • 9

    Chromatin condenses into chromosomes. Each half of the chromosome is a

    Chromatid

  • 10

    The life cycle of a cell is known as the ------, and this describes how cells grow, develop, and reproduce.

    Cell cycle

  • 11

    Three Stages of the Cell Cycle

    Interphase

  • 12

    This stage is named so because it is when the cell synthesizes a copy of its DNA in a very notable process called DNA replication.

    Cleavage furrow

  • 16

    is marked by the formation of a -------- in plant cells.

    Cell plate

  • 17

    refers to the division of the nucleus and genetic material

    Meiosis and mitosis

  • 18

    refers to the division of the cytoplasm.
