Nucleic acids are made of monomers known as nucleotides. There are 3 parts to nucleotides: one of 4 nitrogenous bases, a sugar, and a phosphate group. RNA as well as DNA are both nucleotides. The four bases in DNA are: Adenine, Guanine, Cytosine and Thymine (present in DNA only). Plus a slightly different base: Uracil (present in RNA only). The sugars are deoxyribose (in DNA) and ribose (in RNA). The Phosphate groups plus the sugars form the sides of the ladder as the molecule comes together. The bases are the rungs or steps on the ladder. The entire molecule will form a twisted ladder when fully complete.
Genes
The process wherein messenger RNQ (or mRNA) is given a message is called transcription. In this process, n mRNA molecule is made (or transcribed) using DNA as the template. Essentially, the nucleotide sequence on a gene is read by an enzyme called RNA polymerase which synthesizes the mRNA molecule. Put simply, RNA polymerase scans the length of DNA until a gene is encountered. When the enzyme reaches the correct position, it begins adding complimentary nucleotides to make the mRNA molecule. This way, the entire gene is transcribed and copied on to the mRNA molecule.

The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.

Hemoglobin is a metalloprotein, which is a generic term for a protein that contains a metal iron cofactor. (A cofactor in biochemistry terms is a non-protein chemical compound that is bound to a protein and is vital for the protein's biological activity.)

Oxygen after inhalation is absorbed by hemoglobin of blood in the lungs and from there it is distributed in the entire body through blood streams.

Yes, nucleotides are polar. Nucleotides are the building blocks of DNA and are made up of 3 things - a phosphate group (huge indication that it's polar, it has a negative charge of -3), a 5 carbon sugar (it has polar OH hydroxyl groups) and a nitrogen base (not polar). Overall, the entire nucleotide together is polar.
