As we know that DNA has been the hot topic in Biology. But did we stop to think that it has been the hot topic in Biology for almost 70 Yrs?
DNA was discovered long before watson and crick cracked the way how DNA is organized. and a long time ago scientist isolated tRNA that codes proteins.
the biological world is now going through a shift which will touch the very building block of life, Proteins
Proteins as we know are made out of amino acids and amino acids are coded by something called a Codon.
i forgotten the term but as i know one amino acid can have various codons coding it.
so different lenghts of DNA can practically code 1 single protein molecule.
that is why DNA has its limitation when analyzing fossils. because, if i am not mistaken it can only be acurate for aout 50-60 million years.
but for proteins you can accurately date a sample back as far as 100 - 200 million years.
i was very passionate about science when i noticed that malaysian biotech has no future. so i went into finance instead. but Boy do i miss biology

correction to MR goldfries. we are discussing Proteomics not DNA.
it is something like DNA but unlike DNA proteins are not degenerate: Meaning that one protein molecule cannot be coded by different amino acid
compared to one amino acid is coded by 3 or more DNA codons. potential applications is for prehistoric genetic translation and also gene mapping for ancient DNA>
the limit for DNA is about a few thousand or million years where as the coding for protein is about a few billion years if i not mistaken

chill la. if u cant get a job in malaysia get a job in singapore.
Proteomics is a relatively new science and only a handfull of professors is able to guide you. i only know of 1 which is also from UTAr who was a senior lecturer in louisiana state uni previously before returning to Malaysia.
what i think is that we should drop all earthly needs and just focus on the betterment of humanity.,
for example Dr norman Bourlog. he did not create GM food for money but he created GM food to be able to sustain humanities future. he travels from poor countires to poor countries giving all of his money to the people who needs them .
