Answer;
D. polynucleotide
Explanation;
DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.
Although each organism's DNA is unique, all DNA is composed of the same nitrogen-based molecules. It is simply the order in which these smaller molecules are arranged that differs among individuals. In turn, this pattern of arrangement ultimately determines each organism's unique characteristics.
At the most basic level, all DNA is composed of a series of smaller molecules called nucleotides.
Answer:
Glycocalyx
Explanation:
Most of the eukaryotic cells have a coating outside their cell membrane. This coating is called the glycocalyx. It consists of glycoproteins and glycolipids. The sugar parts of these compounds are in contact with the underlying plasma membrane. The function of the glycocalyx is to protect the cell. Certain specific molecules of the glycocalyx are involved in the recognition of cells so that they can recognize one another to make contact.
