amount of plasma, proteins and blood cells escape

into intercellular spaces in the tissues to form the

tissue fluid or_______.

The Codon AUG has dual functions in the translation

process. One of the functions is that it codes for the amino

acid methionine.

What is the other function?

AUG triggers the translation by acting as a start signal. It is also called the start codon.
