Why do we have so much dna?
jasenka [17]

Answer:

Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up the human genome – the entirety of our genetic material. It is remarkable that each of the over 200 cell types in the body interprets this identical information very differently in order to perform the functions necessary to keep us alive. This demonstrates that we need to look beyond the sequence of DNA itself in order to understand how an organism and its cells function.

Oksanka [162]
<h2>False  </h2>

Explanation:

Alimentary canal components include mouth, pharynx, esophagus, stomach, small intestine and large intestine whereas liver is a component of the accessory digestive system

  • The liver is a large organ that is located in the upper right portion of abdomen, beneath the diaphragm
  • The liver has two large sections, called the right and the left lobes and the gallbladder sits under the liver, along with parts of the pancreas and intestines
  • The liver and these organs work together to digest, absorb, and process food
  • The liver's main role is to filter the blood coming from the digestive tract, before passing it to the rest of the body
  • The liver also detoxifies chemicals and metabolizes drugs
  • The liver secretes bile that ends up back in the intestines and also makes proteins important for blood clotting and other functions
