Difference between amino acid sequence and mrna sequence

The mRNA sequence is made up of nucleotides (G, C, A, U). Every three nucleotides make up a codon, and each codon encodes an amino acid. When mRNA is processed at a ribosome, the amino acids are added, one by one, in the order described by the mRNA to make a protein (which are made up of amino acids)

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
