Explanation:
Answer:
Binds to extracellular structures and is important in cell recognition and lubrication of the cell surface.
Explanation:
They form a peri-cellular matrix around the cell and is observed as a fuzzy cell coat under a microscope. Glycocalyx molecules are mostly made up of carbohydrates bonded with lipids and proteins. They are significant in cell adhesion especially in tissues and for protection in prokaryotes. These molecules are also important in cell-to-cell communication and recognition.
The Answer is C. DNA
Our DNA is responsible to carriy out our genetic information which located in our cell nucleus.
The Scientist previously thought the molecul of inheritance is composed of Lipids (some sort of proteins)
As for RNA, it only carried out genetic information in a couple of viruses. Even most viruses use DNa to carry out its genetic information
“Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. DNA exists in a cell's nucleus within structures called chromosomes .”
