Describe the basic structure of a cell.

Explanation / Answer

Ans: Nucleus

Nucleus is a double membrane structure which stores our genetic material in the form of chromosomes. Nucleus provides protection to chromosomes.

2. What is forensic biology and how does it differ from one other discipline of forensic science?

3. Find an example of a protein disease, name the protein affected, and what the correct protein in a healthy individual should be?

Ans: Alzheimer's disease is a diseased caused due to misfolded protein structure (amyloid beta protein ). Normal function of this protein is to repair and growth of neurons.

Note: tau proteins are also responsible for Alzheimer's.

4. Find an example of a chromosomal disease and name the chromosome affected.

Ans: Down syndrome.

It is caused due to trisomy (three copies of a chromosome instead of normal two chromosomes) of chromosome 21.
