Description
1.Describe why saturated fatty acids have higher melting points than do unsaturated fatty acids that have the same chain length.
2.What is the biological advantage to an organism that stores its carbohydrate reserves as starch or glycogen rather than as an equivalent amount of free glucose?
3.Describe briefly what is meant by saying that two DNA strands are complementary, and write a double-stranded DNA sequence containing a six-nucleotide palindrome.
4.Describe the dependence of the melting point of a fatty acid upon (a) chain length and (b) unsaturation; (c) explain these dependencies in molecular terms.
5.Describe qualitatively how the tm for a double-stranded DNA depends on its nucleotide composition.
