Multiple Choice

Where are chromosomes located in the cell?

• cytoplasm
• DNA

• cell membrane
• nucleus

Multiple Choice

What is the structure of DNA?

• Single-Helix

• Double-Helix

• Triple-Helix

• X-Shaped

Multiple Select

What happens in Prophase (choose 3)

• DNA condenses (packs up)

• Spindle fibers appear

• Daughter cells separate

• DNA lines up in middle

• Nuclear envelope (membrane) dissolves

Multiple Choice

What happens in metaphase? (choose 1)

• DNA splits apart

• Cell divides

• DNA lines up in middle

• New nuclei form

Multiple Choice

What happens in anaphase? (choose 1)

• DNA replicates

• Chromatids pull apart to opposite sides

• DNA lines up in middle

• Cell divides

Multiple Select

What happens in telophase? (choose 2)

• Two new nuclei form

• Daughter cells separate into two cells

• DNA pulls apart to opposite sides

• cytoplasm begins to pinch apart

Multiple Choice

What happens in cytokinesis? (choose 1)

• Daughter cells separate completely as cytoplasm is split into two

• Nuclear envelope dissolves

• DNA separates apart to opposite sides of the cell

• DNA replicates

Multiple Choice

• Cytonkinesis
• Interphase
• Prophase

Multiple Choice

• Cytokinesis
• Interphase
• Anaphase
• Metaphase

Multiple Choice

• Anaphase
• Cytokinesis
• Telophase
• Metaphase

Multiple Choice

• Cytokinesis
• Anaphase
• Telophase
• Prophase

Multiple Choice

What is cell differentiation?

• Process by which cells produce MORE cells.

• Process by which cells become UNSPECIALIZED

• Process by with cells become SPECIALIZED

• Process by which cells become old and DIE

Multiple Choice

What process best explains how muscle cells and nerve cells can develop from the same fertilized egg?

• genetic engineering
• survival of the fittest
• differentiation
• selective breeding

Multiple Choice

What is the difference between embryonic stem cells and adult stem cells?

• Embryonic stem cells can differentiate into more cell types than adult stem cells
• Adult stem cells are pluripotent, just like embryonic stem cells
• Adult stem cells can differentiate into more cell types than embryonic stem cells
• Adult stem cells grow bigger than embryonic stem cells

Multiple Select

The process of a cell developing into a certain type has two names, what are they?

• Replication

• Translation

• Differentiation

• Specialization

Multiple Choice

Cells differentiate to perform different functions because

• all genes are turned on inside that cell

• all genes are turned off inside that cell

• different genes are turned on inside that cell

• different genes are turned on or off inside that cell

Multiple Choice

During the process of differentiation

• all sections of DNA are activated to determine the structure of a body cell

• ONLY ONE section of DNA are deactivated to determine the structure of a body cell

• only specific sections of DNA sequence are activated to determine the structure and functions of a body cell
