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
