Year 10 Genetics and Biotechnology Biology Cell division

Year 10 – Genetics and Biotechnology (Biology) Cell division - Mitosis

Year 10 – Genetics and Biotechnology (Biology) • 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

Year 10 – Genetics and Biotechnology (Biology) Task 1 – animal cells • Draw and label the animal cell Q 1)What is the function of the nucleus? Q 2)What are contained inside the nucleus?

Year 10 – Genetics and Biotechnology (Biology) Storing information Section of a chromosome: • 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

Year 10 – Genetics and Biotechnology (Biology) Task 2: Make a note of key points Chromosome DNA gene • 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.

Year 10 – Genetics and Biotechnology (Biology) Chromosomes • 23 pairs • 46 • Pair 23 = sex chromosomes • XX = female • XY = Male

Year 10 – Genetics and Biotechnology (Biology) Parent cell has 2 pairs of chromosomes Chromosomes are copied Copied chromosomes move to opposite ends of the cell Mitosis basics watch clip Takes place as part of cell growth and replacement Also asexual reproduction Cell membrane starts to divide to form 2 daughter cells Each has identical chromosomes to the parent cell.
