Question

explain the meaning of genatic disorded and givename of some disorders

Answer 1

A genetic disorder is a disease that is caused by a change, or mutation, in an individual’s DNA sequence.

A genetic disorder is an illness caused by changes in a person’s DNA.

These mutations can be due to an error in DNA replication  or due to environmental factors, such as cigarette smoke and exposure to radiation, which cause changes in the DNA sequence.

The human genome is a complex set of instructions, like a recipe book, directing our growth and development.

However, unlike a printed book, the human genome can change.

These changes can affect the individual bases (A, C, G or T) or much larger chunks of DNA or even chromosomes.

Our DNA provides the code for making proteins the molecules that perform most of the functions in our body.

examples of monogenetic disorders include:

cystic fibrosis,

sickle cell anemia,

Marfan syndrome,

Huntington's disease, and

hemochromatosis.

Examples of multifactorial inheritance include:

heart disease,

high blood pressure,

Alzheimer's disease,

arthritis,

diabetes,

Answer 2

Answer:

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs.

Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder.

You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

There are three types of genetic disorders:

Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.

Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. Chromosomes are the structures that hold our genes. Down syndrome is a chromosomal disorder.

Complex disorders, where there are mutations in two or more genes. Often your lifestyle and environment
