Cell Division and Differentiation Concepts

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

Match the following

• Metaphase

• The cell starts to split into two

• Telophase

• Sister chromatid moves apart

• Interphase

• Cell growth, and DNA replicates

• Prophase

• Chromosomes line up in middle of cell

• Anaphase

• Genetic material condenses

DNA Replications uses a specialized enzyme to find the "free-floating" nucleotides and it pairs them with the complementary nucleotide. It helps connect the two new strands of DNA.​

​ (a)   ​ ​

• DNA Polymerase
• DNA Helicase
• RNA Polymerase
