One difference between cell division in plant and animal cells is...

• Only animal cells have a mitochondria
• Plant cells have a cell wall, animal cells do not
• Plant cells do not have a nucleus

Before DNA can replicate, what must occur first?

• DNA must form a double helix.
• The 2 DNA strands must separate or come apart.
• The DNA must leave the nucleus and the cell.

During which part of the cell cycle is the DNA replicated?

• Telophase
• Metaphase
• Interphase

DNA is found in …

• All of the cells in our body
• Our brain cells only
• Stem cells only

A new daughter cell produced during mitosis is identical to …

• The parent cell only but not the other daughter cell
• The other daughter cell but not to the parent cell
• The other daughter cell and the parent cell

In a DNA molecule, the backbone is made up of the sugar and phosphate groups, the genetic information is stored in the bases, and amino acids are connected into a chain.

• The backbone is made up of the sugar and phosphate groups
