Did a lab exp last friday! Isolated my Cheek cell DNA to check for this Alu repeats on chromosome 16! I am homozygous positive for the Alu repeats on my chromosome 16!!! I have 2 chromosome 16 becuz one is from my dad and one is from my mum. Homozygous in this case means having these 2 Alu repeats on both chromosome. Heterozygous on the other hand means that one of the chromosome 16 has this repeats while the other dun.
OMG, i have increased risk of getting cancer!

An Alu sequence is a short stretch of DNA originally characterized by the action of the Alu restriction endonuclease. Alu sequences of different kinds occur in large numbers in primate genomes. In fact, Alu sequences are the most abundant mobile elements in the human genome. Alu insertions have been implicated in several inherited human diseases, including various forms of cancer. T

he Alu family is a family of polymorphisms in the Human genome. Alu sequences are about 300 base pairs long and are therefore classified as short interspersed nuclear elements (SINEs) amongst the class of repetitive DNA elements.
There are over one million Alu sequences interspersed throughout the human genome, and it is estimated that about 10% of the mass of the human genome consists of Alu sequences. However less than 0.5% are polymorphic.


Pris and myself, both of us are having a increased risk of cancer!
Mark from my class also gt the same result as us. He was so paranoid! hahaha. Kept on saying he is gonna die! haha.. Our whole class jacked him in from of the lecturer laa. Making him more paranoid when we said he smoked which increased the risk of cancer too. hahaha. so funny!
