      DNA-RNA-mRNA-amino aicds-polypeptides-proteins.
      is that the correct order.
      also, the primary strcuture of protein depends on the sequence of amino aicds.however the secondar structure of protein come under tow groups, alpha helix and beta arrangement. in alpha helix,the chain of ONE polypeptide is twisted,so that the neigbouring hydrogens bonds interact.while in beta helix, two or more polypeptides run alongside,so that hydrogen bonds interact next to each other.the tertiary structure of a protein is the overal shape?

      anyone can explain wat the difference is between tertiry structure and quantenary strcture?

      by the way, is it really necessary to have so many structures?

      Its
      DNA-mRNA-RIBOSOME-tRNA-AMINO ACID-PROTEINS.

      You are right with your oncept.

      Check google for quaternary and tirtiary structure.

      yes, its necessary to have so many structures, enzyme binding and protein interaction needs specific structure of proteins so that they can work efficiently and separately, and can not jumble up.

      I always learnt them as alpha helix and beta sheets…

      yeah, it’s beta sheet not beta helix, because of it’s actual sheet shape, as oposed to a helical shape.

      I ve studied it as "Beta plate"…………

      it’s beta sheet or beta pleeted sheet. But beta plate is ok if you ask me. The name doesn’t matter that much anyway…

      Tell them to Dr.Stein and she’ll say, They do matter 😆
