1. Cell division - Mitosis

2. I am learning to:
Identify the location of chromosomes and genes in the cell
describe how cells divide by mitosis and why this is important
Label sequence of Mitosis

3. Task 1 – animal cells Draw and label the animal cell
Q1)What is the function of the nucleus?
Q2)What are contained inside the nucleus?

4. Section of a chromosome:
Storing information
Inside the nucleus of our cells are the Chromosomes
Human cells have 46 chromosomes (23 pairs)
Sections of a chromosome are called genes
Chromosomes are coiled strands of DNA
Section of a chromosome:

5. Task 2: Make a note of key points
Chromosome
Chromosomes are made up of large molecules of DNA
A gene is a small section of DNA
Each gene codes for a particular combination of amino acids that make a specific protein.
DNA
gene

6. Chromosomes 23 pairs 46 Pair 23 = sex chromosomes XX = female
XY = Male

7. Mitosis basics -watch clip
Parent cell has 2 pairs of chromosomes
Mitosis basics -watch clip
Takes place as part of cell growth and replacement
Also asexual reproduction
Chromosomes are copied
Copied chromosomes move to opposite ends of the cell
Cell membrane starts to divide to form 2 daughter cells
Each has identical chromosomes to the parent cell.
