Know that DNA contain genetic information of how many creatures, structure of DNA consists of polynucleotide two lines with a length of thousands thousand base pairs. Sequence base there is the difference in various ways.DNA each molecule of different sequence number base is only 4 bass type is A T C G and therefore possible genetic difference of organisms in sequence, and a number of bass. DNA itself. The next problem is DNA sequence.The students know it is organic, there are many kinds of proteins play a role in performance characteristics of shell, such as The shell is โปตีน muscle actin, and myosin. The red blood cells have the protein hemoglobin.Such as synthetic reaction substance and metabolic substances must live enzymes It boldly said that โปต was associated with the genetic material. Both Yeo and living directly and indirectly.
