Q1) sequence of DNA, ultimately determines the unique sequence of amino
acids in each peptide chain. change in nucleotide sequence of the gene's coding
region may lead to a different amino acid being added to the growing
polypeptide chain.
Q2) Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid
molecules. triglyceride is formed when the three hydroxyls groups of a single
glycerol molecule react with the carboxyl group of three fatty acids by forming
ester bonds.
Q3) Its four key properties thermal properties, ability to act as a universal
solvent, cohesion and adhesion help support the life processes and habitats of
virtually all organisms, Water's ability to act as a universal solvent largely stems
from its polarity.
