Answer to relevant QuestionsA membrane consists of 50% protein by weight and 50% phosphoglycerides by weight. The average molecular weight of the lipids is 800 Da, and the average molecular weight of the proteins is 50,000 Da. Calculate the molar ratio ...Consider the following in light of the concept of levels of structure (primary, secondary, tertiary, quaternary) as defined for proteins. (a) What level is shown by double-stranded DNA? (b) What level is shown by tRNA? (c) ...Would you expect to find adenine–guanine or cytosine–thymine base pairs in DNA? Why? Would you expect tRNA or mRNA to be more extensively hydrogen bonded? Why? Can methylation of nucleotides play a role in DNA replication? If so, what sort of role?
