2. WHAT ARE NUCLEOTIDES?
Nucleotides are small organic molecules consisting
of a five ring sugar (which can be a ribose or a
deoxyribose), a nitrogen base, and one to three
phosphate groups. The most important function
of nucleotides is there polymerization in nucleic
acids such as DNA or RNA.

3. WHAT IS THE FUNCTION OF A NUCLEOTIDE?
In addition to their roles as the subunits of nucleic
acids, nucleotides have a variety of other functions in every
cell: as energy carriers, components of enzyme cofactors,
and chemical messengers.

4. WHAT IS THE BIOLOGICAL IMPORTANCE OF NUCLEOTIDES?
Nucleotides are the building blocks that are necessary for
making new DNA and RNA. ... RNA is similar to DNA, except
that the molecule uradine replaces thymine in that pair, and
RNA is an intermediary between DNA and protein. A gene is a
discrete sequence of DNA nucleotides, and genes are what
make up our chromosomes.

5. A PRECURSOR OF DNA &RNA?
DNA and RNA are the molecules that evolution chose to store
all genetic information. But at the time when life began, the
prebiotic soup may have contained other information
molecules, which were ultimately superceded by present day
nucleic acids.

6. ACTIVATED INTERMEDIATES IN MANY BIOSYNTHESES
e.G UDP-glucose glycogen,
CDP-diacylglycerol phosphoglycerides,
S-adenosylmathionine as methyl donor, etc.

7. COFACTOR OF ADENINE NUCLEOTIDE
Adenine nucleotides are components of the coenzymes, NAD(P)+, FAD, and CoA.

8. BIOSYNTHESIS
simple compounds are modified, converted into other
compounds, or joined together to form macromolecules.

9. POLYSACCHARIDE SYNTHESIS
When the cells are grown on a carbon source different than
glucose, then polysaccharides are synthesizedusing a different
pathway. Gluconeogenesis (abbreviated GNG) is a metabolic
pathway that results in the generation of glucose from non-
carbohydrate carbon substrates such as phosphoenolpyruvate
(PEP).
