Drama:

• uploaded and submitted her video

Science:

Structure:

• Pyrimidine: single ring
• Purine: double rings
• Sugar + Phosphate backbone

Inheritance

• Inheritance happens by the parents passing along its DNA

Cell Division Importance

Important because:
- growth: need more cells to grow
- repair: cells break down and need to reproduce
- reproduction: need to create gametes (haploid cells)

DNA terms

Function:

• Mitosis
• DNA is store inside the nucleus

2. Cell Cycle and Mitosis
   

• Male and female twins cannot be identical (gene) twins

Mitosis

3 Asexual Reproduction

• Asexual reproduction:
  • Binary fission - bacteria
  • Budding - hydra
  • Fragmentation - star fish
  • Vegetative Reproduction - grafting cuttings
  • Spore - fungi

Advantages and disadvantages

• Asexual - generally, less energy, don't need to find a mate, can reproduce quickly...; disadvantage, no diversity and can be affected by change in environment
• Sexual - generally, more energy; advantage, more robust to environmental change

Cloning

• embryonic cloning

research:

• can have cells and animal models with known genes/DNA

reproductive vs therapeutic cloning

Benefits and risks of cloning

• you're killing embryos
• killing animals (mouse)
• breakthrough in disease

Meiosis - create haploids

To create genetic variation.

See above.
