I decided to recreate the base paring chart from edwardslearninglab video for those who want a copy of the chart. These charts show the correlations between adenine (A), guanine (G), cytosine (C), thymine (T) and uracil (U).
And between DNA to DNA, DNA to mRNA, mRNA to tRNA in receptive to the columns (right to left).
For my bio-organic chemistry course, the chart above was all one that one could need, this is the core skeleton. I know this since memorizing one more thing was something I did not want to do.
