What letters are other 44 Cromozoms?

I think it goes like this, but I am no expert, even though DNA features highly in my hobby of genealogy.

There are 23 pairs of chromosomes. They are given numbers 1 to 22 plus an XX or XY pair of sex chromosomes.

The letters apply to parts of the DNA double helix. These letters are A, C, G and T, depending on the structure of that part of DNA.

I have donre an Ancestry DNA test, and submitted the resulrs to several other web sites. It did largely agree with my ethnicity as found from primary and secondary records.

Chromosomes come in pairs.

Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father.

Two of the chromosomes (the X and the Y chromosome) are called sex chromosomes, and found in almost all people.

At conception, the mother gives an X chromosome to the child, and the father may contribute an X or a Y. The chromosome from the father determines if the baby is female or male.
