What is in a chromosome and where is it found?
Found in the cell nucleus and contains many genes
1 of 17
What is a gene?
A gene is a section of DNA which carries coding for a particular protien
2 of 17
What is the job of a gene?
Different genes control the development of different characteristics of an organism
3 of 17
Products of Sexual Reproduction?
Children will resemble their parents
4 of 17
Products of Asexual Reproduction?
Clones which are genetically identical to their parent
5 of 17
How many chromosomes does a human sex cell have?
23 (half the number all the other cells in the body do)
6 of 17
What is a gamete?
Sex cells

What are the steps of 'Cuttings' in cloning in plants?
Cut of branch from parent plant, Plant hormones are used to encourage new roots to develop, Cutting is kept moist and warm, after a few weeks new plant is produced
8 of 17
What are the steps of 'Tissue Culture'?
Uses tiny pieces of parent plant, Sterile agar jelly with plant hormones and lots of nutrients are needed.
9 of 17
Problem with Tissue Culture
Very expensive and more difficult to do than cuttings

What are the steps of Embryo Transplants
Developing embryo is removed from pregnant mother at early stage, Cells are separated, Cells are then grown in lab and transplanted into a host mother, when offspring are born they are identical to eachother and genetically related to original anima

First step of Adult cell cloning
Nucleus is removed from an unfertilized egg and discarded, left with empty egg cell
12 of 17
Second step of Adult cell cloning
Nucleus is removed from adult body cell and injected into the empty egg cell
13 of 17
Third step of adult cell cloning
Electric shock is applied to make the egg cell begin to divide and form an embryo
14 of 17
Last step of Adult cell cloning
While it is still a ball of cells the embryo is inserted into womb of an adult female, embryo continues to grow and develop

How does Genetic Modification work?
Certain enzymes can cut pieces of DNA from one organism and join them into DNA of another organism giving it new character istics
16 of 17
What is Genetic Modification used for?
GM crops
