Nucleotides are the building blocks of nucleic acids. In DNA, there are four types of nucleotides each containing one of four nitrogenous bases: guanine (G), cytosine (C), adenine (A), thymine (T).
- The monomer exhibited in the figure is a NUCLEOTIDE, i.e., a purine (Adenine) nucleotide.
- A nucleotide is a molecule composed of a nitrogenous base, a pentose sugar (deoxyribose in DNA) and a phosphate group.
- Purine bases consist of a double‐ring structure having four nitrogen (N) atoms and five carbons (C) atoms.

Answer:
Primary active transport
Explanation:
Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump is an example of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).
Albert Alexander was the first patient to be successfully treated on an infection caused by bacteria. He accidentally scratched a thorn of a rose on his face which badly infected him.

He, however, died on March 1941. </span>
