Biol. 1311 – 9/15/06 – Basics of nucleic acid coding of protein sequence Nucleic acids as information carriers All evolutionary change incorporates a change in nucleic acid sequences A very brief review of nucleic acids (Fig 4.1) Polymerization looks similar to previous chemistries (Fig 4.2) But not identical (fig 14.9) Something more than just H 2 O comes off There is more than basic information in those few letters (fig 15.8) Theses are RNA bases – how do you know? The permanent repository is DNA (fig 15.3) Information is store twice at the same time because of base-pairing (fig 4.9b) From any one strand of DNA the other is prescribed (fig 4.10) Notice that the 2 strands are oriented in opposite directions We will come back to the details of this structure later (Fig. 4.11) Your book calls this a secondary structure – is it? Helix can be unwrapped and new copies made (Fig 4.12) Contrast to RNA which functions as a single linear sequence (fig 4.13) But it can form 3D structures Two functions of DNA

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
