    Good video overall, but serine has only one CH2 in their R group.

    SER is errated. The R group is actually CH2OH :)

    Very well explained!! A fantastic lesson achieved. Just one question teacher, it is a multiple choice in exam that says either amino acid is converted to glycogen to be used in respiration or amino acid is converted to both urea and glycogen?

    If the R chain is hidrofilic because the variance of electonegativity between the oxygen and the hydrogen; it means that the carboxyl group is also hidrofilic?

    DNA doesn't replicate itself. It is code, information. A helicase divides the dna and enzymes prevent the mRNA from tangling and the protein formation for the replication are formed by ribosomes, very complex macro molecular machines.

      I think amino acid is not found in DNA, it is found in cytoplasm where synthesize protein.A simple way eukaryotes In nucleus, DNA to RNA during transcription and in cytoplasm RNA is translated into protein(monomer is amino acid).
