B13 Flashcards
What is variation
The step in natural selection where an offspring is born with a slight mutation or difference which may give it an advantage or disadvantage compared to the other animals from that species
Competition
The process by which living organisms compete with each other for limited resources. A slight variation will either help or hinder an organisms chance at beating his competition
Survival
The increased or decreased chance an organism has of staying alive due to its predators and competition
Reproduction
The chance an organism has to reproduce due to its chances of survival, its variation, and competiton
What is genetic engineering
The process by which scientist can manipulate and change the genotype of organism
What are the key steps in genetic engineering
1)A cell is removed from the pancreas of a human ( enzyme cuts it out).2) The human gene is transferred to a circular piece of DNA taken from a bacterial cell.3) The bacterial DNA is put back into the bacteria cell.4) The bacteria is encouraged to divide.
As it does this, it produces the human insulin which can then be collected.
3 examples of how animals have been genetically mutated
Jellyfish
3 examples of how plants have been genetically mutated
Potatoes have been modified to make more starch and be more resistant to common pests. Soybeans have been modified to produce a healthier balance of fatty acids. Rice plants have been modified to withstand being completely covered in water for up to 3 weeks and still produce a good crop.
