on macromolecules.

Submitted by ekim on Sat, 11/03/2007 - 5:46pm.

this may be a silly question, but...
if macromolecules are organic chemicals that are naturally made and found in living things, then...why do we need to consume more of it (i.e. carbs, protein, lipids/fat) in the food we eat?
do we need to consume more macromolecules in order to produce more within our body? but from looking at the virtual protein synthesis experiment, it seemed like our bodies functioned automatically (in terms of producing protein or whatnot) and randomly.

and speaking of random, if the zipping and unzipping of DNA replication (and passing it on to one's offspring) is random, then what accounts for "better" genes in one sibling than the another sibling? is it pure statistics or luck? b/c if it was really random, then the trend of one sibling having "better" genes would not be as prominent, no?
