DNA is copied because it cannot fit through the nuclear membrane and travel down to the ribosome.
So it is transcribed (translated) to messenger RNA (mRNA). The mRNA can fit through the nuclear membrane and travel down to the ribosome where proteins can be made.
This is why we cannot send the entire DNA molecule itself, it is simply too big to fit. This is why mRNA is extremely important for amino acid production.

Answer:
Yes, the environment and the heritage both plays very crucial role in defining the evolution. But how? let's start it here.
Explanation:
- As per the Charles Darwin theory of natural selection, organisms that better adapt to changes can survive very well.
- For example In earlier times, snakes used to have limbs but they are just useless for them and they are not using those limbs so in next generations snakes have vestigial remnants of limbs.
- Another example we can study here is of mice, such as mice are nocturnal animals so they don't have vision capabilities and over generations they adapt a change due to their predatory nature and came with an affect of better hearing capabilities.
Krypton helps geologist determine the absolute age of a rock
The citric acid cycle – also known as the TCA cycle or the Krebs cycle – is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into adenosine triphosphate and carbon dioxide.
