Cell Cycle

During this phase, the cell grows, develops new organelles, and carries out its normal functions.

• Go of Interphase

• S of Interphase

• Mitosis

• G1 of Interphase

During which phase is the cell "at rest" or "dormant"?

• Go of Interphase

• S of Interphase

• Prophase

• Cytokinesis

During this phase, the cell prepares for mitotic cell division.

• Cytokinesis

• S of Interphase

• G2 of Interphase

• G1 of Interphase

During this phase, DNA is replicated, doubling the number of DNA strands inside of the cell.

• G1 phase of Interphase

• S phase of Interphase

• G2 of Interphase

• Prophase of Mitosis

Which enzyme "unzips" DNA, breaking its hydrogen bonds, to "open it"?

• DNA Primase

• DNA Helicase

• DNA Polymerase

• DNA Ligase

Which enzyme adds nucleotides, based on complimentary base pairing, to the new, growing strand of DNA? (builds the other half of the DNA strand)

• DNA Primase

• DNA Helicase

• DNA Polymerase

• DNA Ligase

What does it mean for DNA replication to be a semi-conservative process?

• Half of the DNA is from the parental strand and half of the DNA is new.

• Two new DNA strands are created.

• DNA is broken down into monomers then built back up to form polymers.

• DNA produces RNA based on complimentary base pairing.

Which of the following is NOT a statement of Cell Theory?

• All organisms are made of one or more cells

• Germs come from ill/diseased tissues

• All existing cells are produced by other living cells

• The cell is the most basic unit of life

Why do Cell Divide? Mark two answers!

• To remain small for diffusion and DNA demand reasons.

• To grow larger cells for increased vigor and efficiency.

• For growth, development, and healing of wounds.

• To maintain a smaller surface area to volume ratio.

What is proliferation?

• rapidly multiplying or increasing in number

• division of internal contents

• to specialize in function

• to be destroyed in a systematic fashion/process
