guys i don't understand this satatement. can anyone explain this?

in a warmer environment, the organism will want to increase its % of unsaturated fatty acids, so that fatty acids will be more fluid and the melting point will decrease.

also, arethe production of t-RNA and r-RNA in the nucleus?

In a lipid bilayer, if you increase the # of unsaturations (ie: double bonds), then you increase the fluidity, thus decreasing the melting point. This is not good for organisms that produce a major source of body heat. Having saturated fatty acids decreases fluidity, thus increasing melting point.

r-RNA & t-RNA are produced in the nucleolus.

Hope that helps.

my take on the first part is that the animals system will want more fluidity so that it will not have to use as much water.

r-RNA is produced on the chromosome and stored in the nucleus and eventuall becomes part of the ribosome.

t-RNA not to sure on this one but definitely not in the nucleus
