|
Students should be able to describe the structure of DNA and define genome. |
|
How is the structure of DNA described and what is a genome? |
|
|
|
The genetic material in the nucleus of a cell is composed of a chemical called DNA. |
|
Where is DNA found in a cell? |
|
|
|
DNA is a polymer made up of two strands forming a double helix. |
|
What is the structure of DNA like? |
|
|
|
The DNA is contained in structures called chromosomes. |
|
How is DNA contained in the nucleus? |
|
|
|
A gene is a small section of DNA on a chromosome. Each gene codes for a particular sequence of amino acids, to make a specific protein. |
|

Sort the order into: Nucleotide, Gene, Chromosome, Genome.
Explain why the order of the bases is important.

(first 3 minutes)
Describe how a gene leads to a protein.
Explain why a base change could change the properties of a protein. |

|
|
The genome of an organism is the entire genetic material of that organism. |

|
|
The whole human genome has now been studied and this will have great importance for medicine in the future. |
|
Why is the study of the human genome important? |
|
|
|
Students should be able to discuss the importance of understanding the human genome. |
|
What is the importance of sutdying the human genome? |
|
|
|
This is limited to the:
- search for genes linked to different types of disease
- understanding and treatment of inherited disorders
- use in tracing human migration patterns from the past. |
|

|
Each nucleotide consists of a common sugar and phosphate group with one of four different bases attached to the sugar |
|
What is the structure of a nucleotide like? |
|
|
|
DNA contains four bases, A, C, G and T. |
|
What are the letters used for the four DNA bases? |
