Genetic Disorder And The Human Genome - 1081 Words

Genetic Disorder is having to do with your health and body. Some people can get it and some people don’t get it every body is different. Now I am going to tell you what a Genetic disorder is, it’s an illness caused by changes or mutation in a person s DNA sequence. The mutation can be caused by an error of the DNA replication. It can also be caused by other things such as cigarette smoke and exposure to radiation which causes the change in the DNA sequence. Now I’m going to introduce the human genome which is a part of the human and body and that is dealing with the DNA sequence. They say the human genome is a set of instructions comparing it to a recipe book directing our growth and development. These changes can affect the individual†¦show more content†¦Then the other one is recessive is an individual has two altered versions of the relevant gene. Then the Xlinked disorder that reflects the presence of an altered gene on the X chromosome. Xlinked diso rders are more common in males because they only have one X chromosome. As a consequences male only need one copy of the altered gene for symptoms to occur. Then it leads into the chromosome disorder which is the number of the changes in the number or structure of the chromosome. An example of chromosome disorder down’s syndrome which they have an extra chromosome which is 21, trisomy 21: three copies of chromosome of 21. Than the 3rd one is multifactorial disorder which is complex disease what it’s a disorder caused by changes in the human multiple gene. Is often in a complex of interaction with the environmental and the lifestyle factors such as dieting and cigarette smoke example cancer. People who have a genetic disorder are born with it and is missing a DNA sequences either the mom was either drinking while she was pregnant with the baby in her or she was either smoking. Another source could be that she was either smoking while she was pregnant , it could also be that it runs in the family somewhere in the gene. It can be many reason that you can have a genetic disorder it can be that the child is just born with it
