Nucleic Acids

Nucleic acids are macromolecules containing the elements…

Carbon, hydrogen, oxygen, nitrogen, and phosphorus

The building blocks of the
nucleic acids are nucleotides.

Nucleic acids
store and
transmit genetic
information.

​

There are two kinds of nucleic acids:
DNA and RNA

2.3 Carbon-Based Molecules TEKS 9A

– Nucleotides are made of a sugar, phosphate group, and a nitrogen base.

A phosphate group

deoxyribose (sugar)

Nucleotides are the building blocks (Monomer) of Nuecleic acids (Polymer)

​

nitrogen-containing molecule,
called a base

Carbon-Based Molecules (Macromolecules)

Nucleic acids = polymers
nucleotides = monomers

Proteins

Proteins are macromolecules
that contain…

…carbon, hydrogen,
oxygen and nitrogen.

The building
blocks of
proteins
are amino

acids.

There are 20 different amino acids.

Each amino acid has four parts. Label these groups
on the drawing above.

Carboxyl group
An amino group
One single hydrogen

An “R” group which is different on
every single amino acid.

Carboxyl

“R” groups

There are many, many uses for proteins
1.

enzymes

2.

hormones

3.

transport proteins such as hemoglobin

4.

contractile proteins such as in muscle
tissue

5.

antibodies

6.

membrane proteins

7.

structural proteins such as bones and
muscles

One single
