Something caught my attention today when I was in class. It�s definitely not how smart looking my classmates were in their formal attire for the upcoming presentation n its definitely not how they combed or styled their hair but something my lecturer mentioned.

He was telling the class bout this news he heard over the radio when he was travelling. It was about DNA testing done in Singapore. Am not sure how true it was, but according to him, it seems like now they can use DNA testing to determine what area or field the kids are good in and the parents can work to mould n encourage them towards that direction.

Based on that itself, it�s really great to be able to excel excellently in their life or what they can do in future by just undergoing such simple testing when they are young. But the question is, wouldn�t they, the kids or the parents that opt for such route be imbalance? Well I�m sure all parents would want their kids to be successful in life and exceptionally outstanding in whatever they engaged in, but wouldn�t the kids be lack of something, when in their early days itself they (the kids) are being �pushed� and directed to do what expected to be really good for them later on in life? Will they be able to grow up enjoying their childhood like any other kids?

I find DNA testing really interesting, aside from how DNA profiles of a mother and father can determine who their child is, how DNA profiles can be used to solve a crime? I�m sure everyone knows the latter one , but how it actually works amaze me!

For instance, after some biscuits were taken from a biscuit tin, the biscuit tin was tested for DNA. Below you can see the DNA profile that was found on the biscuit tin. Jane, Germaine and Katie all say that they have never touched the biscuit tin.

By comparing the DNA profile on the biscuit tin (Figure 1) with the DNA profiles for Jane, Germaine, and Katie (Figure 2), can you tell who touched the biscuit tin?

Figure 1: The DNA profile found on the biscuit tin

DNA on the biscuit tin
Locus 1: 11 14
Locus 2: 10 15
Locus 3: 25 29
Locus 4: 16 17




Figure 2: The DNA profiles of three children

Germaine's DNA
Locus 1: 10 15
Locus 2: 12 14
Locus 3: 24 27
Locus 4: 16 19

Katie's DNA
Locus 1: 11 14
Locus 2: 10 15
Locus 3: 25 29
Locus 4: 16 17

Jane's DNA
Locus 1: 14 16
Locus 2: 11 17
Locus 3: 23 29
Locus 4: 17 20

Answer : Katie's DNA matches the DNA found on the biscuits tin.

DNA is a very interesting subject but is overrated sometimes.

very very interesting, i'm always fascinated by the way DNA works
