DNA & Mitosis

The process in eukaryotic cells of cell division in which the nucleus divides is

• purine

• mitosis

• division

• cellular respiration

What is made during mitosis?

• two identical cells (identical to each other and the original cell)

• one more cell

• dozens of cells

• mutations that change the genes

How many chromosomes do humans have?

• 46
• 21
• 10

In which phase does the cell spend most of it's life?

• Interphase
• Nuclear Division
• Telophase
• Mitosis

Daughter cells always end up with ______ DNA to the parent cell after mitosis.

• different 
• half 
• twice 
• identical 

Which stage of mitosis is shown in the diagram?

• Cytokinesis
• Interphase
• Anaphase
• Metaphase

Before a cell can divide, what must happen?

• Nothing, it is always ready to divide
• The number of chromosomes must be reduced by half
• The  chromosomes must replicate
• The number of chromosomes must triple.

The cell cycle is ______________.

• the process of cells circling throughout the body
• the process of splitting the organelles
• a process where one cell gets energy
• the sequence of stages of growth and division that a cell undergoes

The initial steps in gene expression are modeled below. Double-stranded DNA first unwinds into two strands

Which process and product are represented in Diagram 2?

• Process: transcription; product: mRNA

• Process: translation; product: protein

• Process: replication; product: tRNA

• Process: recombination; product: polymerase

Part of the cell cycle is shown in this simplified model.

This part of the cell cycle is best described as the process that

• duplicates the DNA

• completes cell division

• maintains genetic homeostasis

• synthesizes new molecules
