### Early Earth's Conditions and the Origin of LifeThe conditions on early Earth were considered very harsh, with volcanoes, lightning discharges, radiation, etc. However, we still are able to conceive the possibility that life may have arisen and existed under such harsh primitive conditions. The existence of organisms in extreme environments such as high acidity, salt, temperatures, etc., even today supports the above possibility in conjunction with the theory of Darwinian evolution.**Question:**- True- False **Question:**DNA binds to proteins called histones. Based on your knowledge of DNA (negative charges along the phosphate backbones) and the classification of amino acids based on the properties of the side-chains, which two amino acids would you predict will be more frequently in histones than in other proteins?**Options:**1. Lys and Arg2. Asp and Glu3. Met and Cys4. Trp and Pro5. Gly and Pro

Histones are composed of mostly positively amino acid residues. The positive charges allow them to…

A) Polymer Lipid DNA B) Monomer (or component units in the case of lipids). Draw the specific structure and put the name of the molecule under the structure. Fatty acids (pick 1), glycerol, glycerophospholipid Deoxynucleotide monophosphates (Pick one purine and one pyrimidine) C) Additional tasks Is your fatty acid saturated or unsaturated? How do you know? On your glycerophospholipid, identify the glycerol group, the fatty acids, and the phosphocholine. Label the hydrophilic head and hydrophobic tail. Label which is the purine and which is the pyrimidine. Circle the sugar on each.

In class we learned about the H-bonding pattern in an alpha-helix. Asp 61 of the spidroin CTD has a slightly unusual H-bonding feature within the helix. That is because it forms three H-bonds. They are H-bonds between its carbonyl oxygen and , between its amide hydrogen and , and between its side chain and Hint: by clicking once on the ribbon diagram at any spot, the model will show H-bonding in that spot.
Draw any pentapeptide. All C-O, C-N, and C-S bonds must be written out, as well as all N-H, S-H, and O-H atoms/bonds. Your peptide must include at least one amino acid from each of the major classes of amino acids (i.e. charged, polar, etc.). Circle each peptide bond in this peptide.
