Answer:
DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
Answer: Lipids.
Explanation:
The large carbon -hydrogen bonds(C-H) in chains of lipids makes them ideal storage of energy.
T<u>he more C-H bonds breakage, the higher protons availability from Citric acid cycle NADH and FADH2 and hydrogen atom splitting (to protons and electrons) for the electron transport chains (ETC</u>), and therefore the higher proton pumps for more ATP's synthesis in the mitochondria matrix.
In addition large number of electrons surrounding carbon atom in fatty acids than other food molecule is added factor. The transfer of these electrons to oxygen during oxidation of fatty acids releases large amount of energy (9 kilo calorie) into the cells, more than other food substances

Answer:
Mutations in genetic code occurs when DNA is being duplicated.Any changes in the base pairs leads to mutations by trasition or transversion. Change in amino acid leads to change in sequence and thus, mutation. This si carried on to new generation, if it takes place in germ cells.
RNA travels to ribosomes, after leaving the nucleus, to perform translation and form amino acid with the help of tRNA
